The next U.S. presidential election is being transformed because children everywhere, watching in disbelief as grownups fail to address the climate crisis, are launching their own climate movements.

In contrast to the 2016 election – where exactly zero questions about global warming were posed during the general election debates – the lineup of presidential candidates are already being pressured to do something about the climate threat, and it’s our kids doing it.

Of the two largest youth climate movements in the United States, one originated here and one abroad.

The Sunrise Movement is a student-led political organization which sprang up prior to the mid-term elections to advocate for transitioning to renewable energy. Half of the 20 candidates Sunrise supported for refusing to accept fossil fuel money won election.

Now, Sunrise is aggressively promoting the Green New Deal (GND), a congressional resolution outlining an ambitious economic stimulus package to drive down greenhouse gas emissions while creating green jobs and addressing income inequality. It’s nothing short of an economic and social revolution.

That children confronting an elected official for not supporting the GND can deliver a powerful political gut punch was driven home when Senator Diane Feinstein’s condescending response to young activists went viral.

Mankind has only 12 years left to make unprecedented cuts in greenhouse gas (GHG) emissions if we want to stave off unimaginably catastrophic effects of runaway global warming. This is the warning detailed in October’s report from the United Nation’s Intergovernmental Panel on Climate Change (IPCC), the recognized global climate authority which represents the investigations of hundreds of climate scientists and 195 participating nations.

A 2.0 degree Celsius average global temperature rise above pre-industrial levels was previously viewed by the IPCC as the tipping point beyond which global warming would spiral out of control with incomprehensibly negative consequences for humanity and the planet. We are fully half way to this cut-off, but more to the point is the revised projection by the IPCC that the worst effects will emerge with a smaller temperature rise of just 1.5 degrees Celsius (2.7 degrees Fahrenheit). Preventing the 1.5 degree rise necessitates, by 2030, a 45 percent reduction in GHG emissions compared to 2010 levels, with “net zero emissions by 2050” which means all emissions need be balanced by removal of an equivalent amount from the air.

If GHG emissions continue instead at the current rate, the 1.5 degree mark will be reached in 2040, producing environmental havoc that effectively ensures the end of civilization as we know it. Picture a future defined by poverty, food shortages, coastal flooding, mass migrations, ferocious storms, bigger and more intense wildfires, plus unrelenting heat that makes parts of the world unlivable.

Hearing this, Americans should be screaming from the rooftops, demanding to know how our government will prevent this very real existential threat to our own and our children’s future.

Calif. District 45:  Climate Change? Who Cares?

California Congressional District 45

The California Primary contest for the “top two” candidates in Congressional District 45 is over.  On November 5, incumbent Rep. Mimi Walters will be facing UCI law professor Katie Porter. The City of Irvine lies entirely within District 45, and the fact that Irvine residents comprise 40 percent of the district’s population means Irvine voters are extremely important to determining who will win.

The voters whom both Walters and Porter need to attract are increasingly concerned about climate change. Fully 73 percent of registered voters believe that climate change is happening, and 59 percent believe it is mostly caused by human activities, according to the latest national poll. At the constituent level – even if not in the halls of Congress – climate change has become noticeably less “political.” Belief in human-caused climate change is still strongest among Democrats, but now includes a significant majority of liberal/moderate Republicans as well as voters with no party preference (small “i” independents). “Worry” about climate change has even increased by 7 points among conservative Republicans since just last October.

In November, residents within California’s 45th Congressional District will be deciding whether to entrust Mimi Walters with a 3rd term in the House of Representatives. She is facing a tough reelection battle, so in a race where every vote counts, it’s incumbent upon voters to take a serious look at her performance record before entering the polls.

Because the projected impacts of unchecked global warming are so dire, climate change has become the number one challenge facing humanity. Worsening storms, droughts and wildfires, catastrophic sea level rise, mass species extinction, disrupted food supplies and political and social unrest are all in the offing if we fail to transition from a fossil fuel economy to one based on renewable energy sources.

Though poorer communities and nations will be impacted most, material wealth cannot guarantee that our children and grandchildren will be spared serious consequences.

The years 2016 and 2017 were the first and third hottest on record, respectively. Many residents of Orange County have personal stories of how climate change is already touching their lives.

The Yale Program on Climate Change Communication tracks public opinions on climate change, down to the individual district level. It turns out that California’s 45th is very much in step with the nation as a whole: 71 percent in the district believe climate change is happening, 74 percent want carbon dioxide regulated as a pollutant, and 72 percent believe future generations will be harmed.

As a public servant, Mimi Walters is obligated to represent the views of her constituents, especially on an issue as vital to public security and prosperity as climate change. But, does she?

Though President Trump has withdrawn the U.S. from the 2015 Paris Climate Agreement, this is no time for the 70 percent of Americans who believe climate change is happening to recoil in defeat. Rather, we should feel empowered that a 2016 post-election poll of registered voters found that majorities of Democrats (86%),  Independents (61%) and Republicans (51%) alike wanted the United States to participate in the accord and that two out of three voters said the U.S. should reduce its greenhouse gas emissions regardless of what other countries do.

Thus, it is exactly the time to speak out against the misguided actions of The White House by taking decisive steps well within our reach as individual citizens and communities. After all, the Paris Agreement is only a broad-stroke commitment from participating countries to collectively limit global warming to 1.5 to 2.0 degrees Celsius (°C) compared to preindustrial levels. It has always been true that only Congress and legislative bodies at the state and local level, not the President, can enact laws that can move us from a fossil fuel to a sustainable energy economy.

Here’s what’s happening at various jurisdictions around the nation already.

Irvine: The Little Engine That Could

Irvine led on restoring the ozone layer and should lead now on climate change.

Ozone Depletion: The First Global Environmental Crisis

The depletion of the protective ozone layer in the Earth’s atmosphere by man-made chemicals was the global community’s first environmental crisis.  Today, climate change, largely attributable to greenhouse gas emissions from burning fossil fuels, is the second and far more frightening crisis.

The people of Irvine can be proud that actions taken by the City Council in 1989 were instrumental in creating a blueprint at the local level for carrying out the aspirations set forth in the 1987 Montreal protocol, the international agreement to restore the ozone layer.  It is widely hailed as the most successful global environmental treaty ever.  As the global community today faces the reality that unchecked global warming could unleash catastrophic effects impacting all future generations, Irvine can and should resurrect the same purpose and determination that inspired the City to make a difference back then.

In 1974, scientists at UC Irvine, led by Nobel laureates (1995) F. Sherwood Rowland and Mario J. Molina, predicted that the Earth’s protective ozone layer would be seriously diminished by the rampant use of halogens — chemicals, such as CFCs (chlorofluorocarbons) and other ozone-depleting compounds then used as refrigerants, spray can propellants, and solvents.  The ozone layer acts as a shield, preventing the most harmful ultraviolet radiation in sunlight (UVB) from reaching the Earth’s surface.  Excessive exposure to UVB is known to cause not only sunburn, skin cancers and cataracts but also damage to crops and reduction of plankton populations vital to the ocean food web.

It wasn’t until 1985 that the infamous hole in the ozone layer over Antarctica was discovered, as Rowland and Molina predicted. That triggered the international alarm that led to the Montreal Protocol.  Because action at the federal level was painfully slow in coming, the Irvine City Council, then led by Mayor Larry Agran and City Councilmember Cameron Cosgrove, boldly passed the most far-reaching, legally enforceable measure anywhere to eliminate CFCs and other ozone-depleting substances.  This remarkable ordinance prohibited using CFCs and other targeted halogens in most industrial processes in the City of Irvine.

The City Council, in taking responsible action at the local level, believed that other jurisdictions would be empowered to use Irvine’s ordinance as a model.  That is exactly what happened in many cities and counties across America and throughout the world, and today we know that the hole in the ozone layer is shrinking and we have overcome that global environmental crisis.

Luckier Americans are insulated from many everyday worries, like struggling to pay the rent or mortgage on time. Some even enjoy life in gated communities, fine dining and first-class travel. But, just as money is no guarantee of happiness, neither is it assurance of protection against all of the frightening impacts of unchecked global warming.

2016 was the third straight year that the Earth’s temperature was the hottest on record. Contrary to what one might hear in politicized discourse, climate scientists are nearly unanimous in concluding climate change is happening and is the result of burning fossil fuels for energy.

The United Nations and scientific organizations worldwide warn that effects of climate change are already being felt and that the Earth is more than half the way to a temperature increase of 2 degrees Celsius, beyond which runaway global warming will produce irreversible, catastrophic effects. Even worse, if global greenhouse gas emissions remain on their current trajectory, children living today can expect to experience the fallouts of a temperature increase topping 4 degrees Celsius by end of this century.

Despite such dire predictions, Americans, rich and poor, overwhelmingly believe climate change is not a threat to them personally. In a nationwide, county-by-county poll conducted in 2015, in not a single county did the majority of respondents believe climate change will affect them personally, though majorities in 99% of counties felt future generations would be.

The difficulty Americans have in understanding their own vulnerability to climate change stems in part from failing to see beyond the direct effects of climate change – heatwaves, droughts, storms and floods – to appreciate all the indirect effects on health and safety from air pollution, spread of infectious diseases, food and water shortages, population migrations and conflicts.

These indirect effects of climate change place everyone at risk.

Climate Change Fixers’ Bag of Tricks

Bag of tricksHalting global warming is the chief environmental challenge of our time.

While heat-trapping carbon dioxide (CO2) is not the only greenhouse gas (GHG), it’s the most abundant and longest-lived in the atmosphere and contributes the most to global warming.  In March, atmospheric CO2 content reached a new high of 400 parts per million, already past the 350 limit many scientists believe is a safe level above which we risk triggering irreversible consequences out of human control.

Second only to China as the largest CO2 emitter, it’s incumbent on the United States to lead the world in addressing global warming.  The Intergovernmental Panel on Climate Change estimates that the window of time to avoid the worst effects is just a few decades.  Yet the United States has not adopted even a nationwide strategy.

Neither producers nor consumers of energy from fossil fuels pay for the environmental and social damages wrought.  These so-called externalized costs are shouldered by the public through illness, droughts, violent storms, coastal community destruction, international conflicts, etc.  Externalizing the costs of fossil fuels keeps their market price low, de-incentivizing society to move to renewable energy sources.

Current strategies to wean off fossil fuels fall into four categories.*  Each attempts to internalize the actual costs of burning fossil fuels through incentives to convert to cleaner energy.

More and more Americans are taking responsibility for their personal contribution to global climate change by driving fuel efficient cars, insulating their homes and switching to energy efficient lighting and household appliances.

However, even someone that’s gone to the extremes of traveling only on foot or bicycle and forsaking home heating, cooling, lighting, food refrigeration and cooking will likely shrink their carbon footprint by only about a third.  That’s because roughly two-thirds of Americans’ greenhouse gas (GHG) emissions are embedded instead in consumption of other goods and services, according to a recent analysis by the Center for Global Development (CGD), a non-profit policy research organization.

Most of us attribute our GHG footprint to the easily discerned energy we consume for personal transportation and home utilities.  Yet these so-called “direct” emissions account for just 36% of the average American’s annual GHG emissions which are equivalent to 21.8 tons of CO2.

The remaining 64% of GHG emissions are “indirect” and produced during the manufacture and production of literally everything else we consume, such as food, shelter, clothing, furniture, cars, bicycles, appliances, electronics, pets, toys, tools, cleaning supplies, medications, toiletries, entertainment and air travel.  The fact that indirect emissions typically take place somewhere distant and out of our sight, like in a factory overseas and during transport of products to the point of sale, underlies our lack of connection to them.

Studies abound linking the increase in extreme weather-related catastrophes in recent decades, like droughts, floods, hurricanes and blizzards, to global climate change.

Climate experts stress the urgency of addressing the problem now, predicting cascading economic and political, social and environmental upheavals worldwide if action is delayed. Since the dawn of the industrial revolution, the CO2 content of earth’s atmosphere has shot up from 275 ppm to over 400 ppm, already well above the 350 ppm limit some scientists believe is a safe level above which we risk triggering irreversible consequences out of human control.

Most Americans agree with the climatologists who believe that climate change is happening and likely caused by greenhouse gases produced by the burning of carbon-based fossil fuels. Asked if “the federal government should act to limit the amount of greenhouse gases U.S. businesses put out,” 78% said yes in a national poll which appeared January 20 in The New York Times. This reflects 60% of Republicans and 87% of Democrats polled.

Yet Congress is still home to a cadre of climate change deniers. Even among the majority in Congress that don’t dispute it, previous legislative proposals to price carbon emissions can be counted on two hands and all died in committee, revealing a glaring lack of political will to tackle this perceived global threat. This comes as no surprise given that fossil fuel industry lobbyists are well represented among the paid lobbyists on Capitol Hill which outnumber members of Congress 4-to-1.

Enter the Citizens’ Climate Lobby (CCL), a non-profit, non-partisan advocacy organization populated by volunteer citizens with a single mission: Create the political will in Congress to pass a real solution to climate change, palatable to politicians across the political spectrum.

Meat Lovers Guide to a Friendlier Climate-Change Diet
by Sarah (Steve) Mosko, PhD

Appeared:

A plant-based diet beats a traditional meat-based one hands down when it comes to trimming one’s contribution to greenhouse gases, but not everyone is willing to plunge head-long into a life of tofu dogs and bean burgers.

No doubt there are even plenty self-proclaimed vegetarians out there who guiltily sneak in some fried chicken, pork chops or a tuna melt from time to time and face self-recriminations afterward for satisfying such cravings at the expense of a warming planet.

The good news for either lapsed vegetarians or meat eaters with an environmental conscience is that meats and dairy products are not all created equal when it comes to the quantity of greenhouse gases (GHG) produced. In fact, a study just released by the non-profit organization Environmental Working Group (EWG) and titled “Meat Eater’s Guide to Climate Change + Health” reveals that by avoiding just the three worst GHG offenders – lamb, beef and cheese – even hardcore meat eaters can make a sizable dent in their diet’s climate change footprint.

EWG, in partnership with CleanMetrics, an environmental analysis firm, examined the “cradle to grave” lifecycle, from farm to retail to plate to disposal, of 20 popular foods in four categories – meats, fish, dairy and vegetable protein – and compared the GHG produced by each.

Americans today are generally aware that we consume far more energy per capita than most of the world’s peoples, over four times the world average and double that of regions like Japan and Europe which enjoy a similar standard of living. Most of us reflect on home gas and electric bills plus the fuel pumped into our cars’ gas tanks when judging our personl energy footprints.

But in reality it is all the “stuff” Americans accumulate that contributes most heavily to our total energy consumption. To understand why this is true, it is necessary to first get a handle on the ways societies utilize energy.

By convention, the energy-consuming activities of society are divided into the four sectors described below: residential, commercial, industry and transportation. The pie chart below shows the percentage of total U.S. energy delivered in a year to each sector, according to recent U.S. Energy Information Administration figures. Note that the very same pie chart describes the average per capita energy consumption of Americans in the four sectors.

The residential sector reflects the energy used to run our homes (to power lighting, appliances and heating & cooling systems) and, at 15 percent, it is the next to smallest pie piece. At 40 percent, the transportation sector is largest but includes all energy inputted to move both people and goods about, be it by car, truck, train, plane, boat or pipeline. Given that about half this amount goes into shuttling people, this means that personal transportation and running our homes together account for only about 35 percent of the energy we Americans use.

How much are you willing to pay for access to clean air and drinking water?

What’s a fair price to keep toxic chemicals out of the food supply, to insure the future of ocean and freshwater fish stocks, to keep public parks open, and to stem the melting of the polar ice caps so our coastal cities remain above sea level and polar bears won’t go extinct?

Questions of this sort prompted me to investigate how much the federal government and my home state of California (and ultimately we taxpayers) actually spend on environmental protection. Turns out neither comes close to one thin dime on the dollar.

Federal outlay for environmental protection is one percent
Federal environmental spending, like defense spending, comes under discretionary spending which in 2009 amounted to $1.2 trillion or about one-third of the total $3.5 trillion federal outlay. Mandatory spending makes up the remaining two-thirds of the federal budget (nearly $2.3 trillion) and goes to hefty programs like Medicare, Social Security and interest on the national debt.

Discretionary spending is divided into two broad categories, national defense and non-national defense, with defense spending eating up 53 percent of all discretionary dollars in 2009. The government keeps tabs on federal environmental spending in a category called natural resources and environment (NRE) which totaled $35 billion or just 2.8 percent of discretionary spending and a meager one percent of total federal spending.

What this means in dollars and cents spent on behalf of each person in the country is easy to compute using the U.S. Census Bureau estimate that the country’s population in 2009 slightly exceeded 307 million: Per capita federal spending for NRE was just $114.49, dwarfed by the $2,139.24 spent for every man, woman and child on national defense.

That’s just 31 cents per day spent on my (or your) behalf to preserve the environment versus $5.86 spent daily in one’s name for national defense.

Does the prospect of spending a weekend away from your favorite e-gadgets (cell phone, laptop, iPod or PDA) stir up separation anxiety?  Around our house we’ve dubbed this e-angst, and it can kill enthusiasm for an otherwise welcome family camping vacation.

For teens or adults similarly infected with e-angst, a diversity of devices are on the market which let you bring your e-gadgets along with you camping and also trim your carbon footprint because they utilize only sunshine for power.

Solar chargers
An assortment of portable solar-powered chargers is available that adapt to virtually any handheld electronic appliance including digital cameras and GPS units.  Most rely on photovoltaic silicon cell technology akin to what is used on rooftop solar panels.  Many are small enough to fit in a back pocket or certainly a glove box so can travel with you virtually anywhere.  The cost is as little as $15 on up to $150 depending on the capacity.  Because rechargeable batteries are incorporated, gadgets can be recharged even after the sun goes down.  Small electronics generally charge in 2-4 hours.

Eliminating indoor air pollution can be as simple as dotting your house or office with potted plants, according to research stretching back as far as the space program of the 1980s.

It’s a widely held misconception that staying indoors avoids exposure to air pollutants. Indoor air quality, in fact, is usually worse because contaminants that emanate from a vast assortment of consumer products add to the pollution that drifts in from the outside.

Given that urban dwellers pass 90% of their time inside, any strategy to improve indoor air quality is of widespread interest, especially one as appealing and environmentally sustainable as adding potted plants to the décor.

    My solar roof cost $15,000 to install after rebates and tax breaks, but the value of the house increased by $20,000 and the power bills decreased to $0.

    I was pretty clueless when I recently installed photovoltaic (solar) panels on the roof of my house. All I knew was that all forms of energy consumption contribute to global warming (not just driving) and that I wanted to be part of the solution. I was nothing short of giddy when the “consumption wheel” on my electricity meter started turning backwards for the first time, veritable proof that I was generating more electricity than I was using. Energy was flowing from my rooftop right onto the grid.

    Elation soon gave way to curiosity, however, just like after I had purchased a hybrid Prius and could not help but experiment with ways to maximize my gas mileage. My new passion centered on how to insure an energy surplus on my next electric bill. Switching out the incandescent light bulbs in my house for energy saving compact fluorescent ones was a no brainer.

    At first glance, surfing might seem like an inherently earth-friendly sport. Surfers paddle out and catch waves by sheer force of will and muscle. No need for fossil fuel-burning speed boats to get around. And, surfers have a reputation for caring about ocean pollution.

    But a closer look reveals that, like most human activities, the environmental impact is far from nil and, consequently, there’s a nascent movement within the surfing industry to clean up it its act.

    The Essentials
    The bare necessities of surfing are surfboard, wetsuit, good waves and wheels to and fro. The waves are courtesy of Mother Nature, but the choices surfers make to otherwise outfit themselves determine the toll on the environment.

    Schwarzenegger’s Latest Scorecard on the Environment?
    Mixed as usual

    by Sarah S. Mosko, Ph.D.

    Governor Schwarzenegger

    Gov. Schwarzenegger hosted a summit on global climate in November, 2008 in Los Angeles.

    Throughout his tenure as governor, Arnold Schwarzenegger has earned mixed reviews from the environmental community for his positions on environmental issues. Last September, during the final throes of the 2007-2008 legislative session, reactions again ranged from standing ovations for his signature on groundbreaking new protections against hazardous chemicals to cries of foul play for the veto of legislation to clean up polluted air in the state’s port cities.

    The following highlights the fate of several bills impacting California’s environment as they passed through the governor’s desk in the eleventh hour.

    Toxic Chemicals
    Roughly 100,000 chemicals are in use today, most without any environmental or human safety testing under antiquated federal regulation dating back three decades.

    Stay Married to Stay Green
    by Sarah S. Mosko, Ph.D.

    If you are looking for reasons to patch up a rocky marriage, here is one you have probably overlooked – do it for the planet! While it is common knowledge that divorce can be costly to the pocketbook, a recent investigation exposes pretty hefty costs to the environment too.

    Divorce is on the rise in the United States as evidenced by an increase in divorced households (households with divorced heads) from 5% to 15% of total households between 1970 and 2000. The proportion of married households (with married heads) sank from 69% to 53% over this same interval.

    One spouse typically moves out during a divorce. Michigan State University researchers Eunice Yu and Jianaguo Liu hypothesized that this splitting of families should translate into more but smaller households with loss of resource use efficiency on a per person basis. Their predictions were in fact borne out by tapping into the largest publicly available census based on individual U.S. households – the Integrated Public Use Microdata Series-USA.

    Better Food Choices Get Better Results in Global Warming Battle than Food Miles Reduction

    California Certified Farmers' Markets let genuine California farmers sell their fresh-picked crops directly to the public in over 500 communities throughout the state.

    “Buying local” has become a mantra of many committed to shrinking their personal climate footprint by limiting the miles their food travels from producer to plate. The increasing globalization of food supplies has served to fan this trend.

    However, a new study finds that what you eat has a far greater impact on greenhouse gas (GHG) emissions than where that food was produced. What’s more, saying no to red meat and dairy products even one day a week matters more than buying local all week long.

    Number crunchers Christopher Weber and Scott Matthews at Carnegie Mellon University drew on U.S. government statistics from 1997 to expose the entire life-cycle GHG emissions associated with the diet of the average American household.

    Emissions fell into one of four categories, starting with upstream supply chain transportation wherein equipment and supplies are supplied to food producers. Then comes the food production phase, followed by final delivery transportation from point of production to retailer. The latter is synonymous with so-called food-miles that are the focus of advocates of buying local. The fourth source of emissions occurs during wholesaling and retailing and includes store heating and air-conditioning and food refrigeration.

    Zero Waste!
    Let’s Get Out of This Dump

    by Sarah S. Mosko, Ph.D .

    We are a throw-away society

    Our throw-away habits are making a dump out of our world.

    A fond memory from my childhood is of visiting the neighborhood “dump” with my dad to drop off whatever refuse, like old tires, we could not burn in our backyard incinerator.

    Nowadays, the local dump has been supplanted by centralized landfills, and major restrictions have been placed on backyard incineration. Our waste stream has been transformed also since the introduction of petroleum-based plastics, single-use disposables, and packaging excess. Too, products once designed for durability and repair have been replaced with flimsier versions intended to be tossed and replaced.

    In short, we have become a throw away society. Read the rest of this entry »

    It is a widespread misconception that staying indoors avoids exposure to air pollutants.

    Indoor air quality, in fact, is generally worse because contaminants that arise from a vast assortment of consumer products add to the pollution that drifts in from the outside. Given that urban dwellers pass 90% of their time inside, strategies to improve indoor air quality are of interest to nearly everyone.

    Indoor Air Chemistry
    The chief forms of pollutants generated indoors are known as volatile organic compounds (VOCs) that off-gas primarily from common petroleum-based products. They are impossible to avoid since the sources are nearly endless: furniture, carpeting, paints, varnishes, paint strippers, synthetic building materials, air fresheners, cleaning solutions, toilet bowl deodorizers, personal care products, tobacco smoke, pesticides, and solvents in inks and adhesives.

    The number of VOCs is also long – the U.S. EPA indicated that more than 900 had been identified in indoor air in a 1989 Report of Congress. While some pose no known danger to health, others are Read the rest of this entry »

    Foam cups and other food containers made from polystyrene are outlawed in Laguna, a first in Orange County.

    “To-go” orders in Laguna Beach soon will have a new look because of a city ordinance passed last month prohibiting restaurants from using any polystyrene (PS) for food service cups and containers . . . an Orange County first.

    Polystyrene (PS) is most recognizable in its foamed form (expanded polystyrene or EPS) as hot cups, food clamshells or packaging materials, although non-expanded PS is also made into clear plastic food containers. Restaurants have until July to come up with replacements, e.g. paperboard or a plastic that is biodegradable or easier to recycle.

    The Green Burial Council has contacts in many states who are willing to accommodate green burial.

    There’s one topic that people like to think about even less than what they owe in taxes or the most humiliating thing they have ever done — funerals and burials, especially their own.

    We avoid it not just because it brings up the really big questions (Why are we here? Is there life after death?), but also because we feel no connection to the whole mortuary scene — the cold sterile slab, the smelly embalming fluids, the dreary funeral parlor. These facets of modern burials say nothing about us, or the values we hold.

    But there’s a movement afoot to offer an alternative that is less impersonal and, for many people, more meaningfully connected to the life that was lived. It is called green burials.

    Green Hot Cups

    Hot Beverage Cups Go Green
    (#12 of the Plastic Plague Series)
    Sarah S. Mosko, Ph.D.

    If your paper cup has a plastic lining, it will end up in the landfill.

    If your paper cup has a plastic lining, it will end up in the landfill.

    For the very first time, certain paper packaging products with a shiny resin lining are being produced that can be recycled or composted.

    The obstacle to recycling and composting has been the petroleum-based polyethylene moisture barrier that lines hot coffee cups and many other paper food/drink packaging containers.  Since the polyethylene resin resists biodegradation, it fails to meet standards for compostability and is an unacceptable contaminant that precludes diversion to the paper recycling waste stream. (Click for related article).

    A paper hot cup is the first in a series of novel resin-lined paper products dubbed “ecotainers” that are being rolled out in a joint effort by two companies, International Paper and DaniMer Scientific. The new cup lining is based 99% on the corn-derived resin called PLA (for polylactic acid) that has been tweaked chemically to produce a coating that sticks well to paper (PLA alone sticks poorly). Part of the good news is that petrochemicals do not contribute to the 1% of synthetic chemicals added to the PLA, according to DaniMer’s President. The hot cup not only meets international BPI (Biodegradable Products Institute) standards for compostability, but is also “repulpable” so can even be recycled in the paper waste stream. Look for cups bearing the logo of Green Mountain Coffee Roasters who are the first to adopt the new technology.

    A second fully biodegradable & compostable hot cup on the market has solved the polyethylene lining dilemma by eliminating the lining completely. Brought to us by World Centric, the cup is made from 100% bagasse, the sugarcane fiber left over once the sugarcane juice is extracted. The cup comes without a label and sports a less high-tech look and feel than theecotainer. Although it is soak proof, hot beverages do create some “perspiration” on the outside. However, some big environmental pluses might easily make up for these esthetic drawbacks. Bagasse is sometimes eliminated by open-air incineration after the sugarcane juice is extracted, so converting it into cups both makes more complete use of a natural resource and rids a source of air pollution. Plus, no trees are ever cut down!

    Forward looking companies as described here will no doubt continue their quest for the perfect, environmentally friendly hot cup and make it available to retailers. Now it is up to us consumers to tell our favorite gourmet coffee stores that we want our cup of coffee “green” whether we drink it black or with cream!

    There is a wellspring of hope that 2007 is the tipping point in the fight against global warming.

    This is the year that the hundreds of experts on the Intergovernmental Panel on Climate Change concluded, with near certainty, that global warming is for real. It is the year Al Gore’s documentary An Inconvenient Truth turned “greenhouse gases” into an everyday household expression.

    With the finger of blame pointing squarely at the reckless burning of fossil fuels, renewable energy has become the hottest of topics. Whereas renewables of every ilk will most likely fill important energy niches, solar energy dwarfs all others in ultimate potential because of the sheer abundance of sunlight.

    Global energy consumption in the year 2004 averaged about 15 trillion watts (terawatts, TW), according to the U.S. Energy Information Administration. The amount of sunlight reaching the earth’s surface (120,000 TW) literally exceeds this global demand thousands of times over. In fact, Read the rest of this entry »

    Global warming is on the tip of many tongues these days, but so are hamburgers, pork chops, and fried chicken. As hybrid car sales are up and SUV sales on the decline, it seems Americans might be waking up to the reality that each of us bears some responsibility for climate change through our everyday consumer choices. John Robbins, the once heir-apparent of the Baskin-Robbins ice cream company, has authored bestsellers, such as The Food Revolution, detailing the detrimental environmental impacts of a meat-based diet. He and other experts make a strong case that food choices rank right up there with what car you drive in determining your personal contribution to global warming. A quick look inside the hamburger bun easily makes the point.

    Did you ever notice the shiny lining on the inside of those paper cups designed for hot beverages . . the ones you get at your favorite specialty coffee store? Although the lining’s purpose is noble (prevents the liquid from seeping through the paper), its presence is the very reason those paper cups all end up in landfills.

    Manufacturers tell me the lining is typically a polyethylene resin or some other petroleum-based emulsion. As such, it is a contaminant that prevents recycling as a paper item, and like petroleum-based plastics, it doesn’t biodegrade so is not appropriate for composting.

    Such resins also coat milk cartons and many paper picnic products, thus preventing you from putting them in your curbside recycling bin or your backyard compost.

    Whether you are a career fisherman, weekend angler, surfer, snorkeler, skinny dipper, fish dinner connoisseur, or simply a never-gets-wet admirer of the ocean’s majesty, there’s nothing but bad news coming from recent assessments of the ocean’s health.

    The scope and severity of the ills that experts report have made commonplace the phrase “collapse” in reference to the global loss of sea life and ecosystems. The assaults that appear responsible all stem from human activities, including over-fishing,  deforestation, overdevelopment of coastlines, overuse of pesticides  and fertilizers, oil spills, and general use of the ocean as a dumping ground for sewage, industrial chemicals and other human wastes.

    As of Dec. 2006, plastic toys and childcare products containing either of two chemicals known to disrupt sex hormones will no longer be manufactured, distributed or sold in San Francisco.

    One targeted substance is bisphenol-A, the building block of polycarbonate plastics (#7) used to make some baby bottles, teethers and toys. It is an estrogen mimic that has been linked to miscarriage, birth defects, diabetes and prostate cancer. Leaching of bisphenol-A from polycarbonate bottles or containers into the contents has been documented.

    Also banned are several plasticizers called phthalates added to PVC (#3, polyvinyl chloride) plastic products to make them soft and squishy. Many children’s toys and teethers contain phthalates that can migrate out since they’re not chemically bonded to the plastic polymer. Phthalates interfere with testosterone during fetal life, and exposure has been linked to abnormal reproductive organ development, infertility, premature breast development, shortened pregnancy, and asthma.

    In the Jan. 2006 State of the Union address, President Bush finally admitted that “America is addicted to oil.” He pointed out the need to improve energy and fuel efficiency and reduce our dependence on foreign oil, but said nothing about how our mindless consumption of petroleum-based plastics is symptomatic of this national malady.

    However, just a few facts suffice to illuminate the seriousness of our unhealthy relationship to plastics.

    Since the mid 20th century start of the plastics explosion, consumption of plastics has skyrocketed to the point that the weight of plastics produced in a year in our country is twice the weight of the entire US population.1 And as is true for any addiction, we live in denial about our problem…denial that plastics are non-biodegradable and denial of the threats they pose to the environment and human health (see previous articles in this series for details).

    Our denial is so complete that we’ve allowed plastic debris to accumulate to frightening levels in our oceans – some parts of the Pacific have 6 times more plastic than zooplankton.2 We’ve created a society where just about everything is made out of plastic without taking responsibility for the impact on our own health and the health of the planet.

    Bioplastics. They gotta be better than petroleum plastics, right? A short list of problems linked to petroleum plastics includes oil spills, release of toxins during synthesis, exposure to endocrine disrupting chemicals during routine use, threats to wildlife from ingestion or entanglement, environmental pollution during disposal, and maybe even a basis for wars as global petroleum supplies dwindle. Furthermore, petroleum plastics do not biodegrade, creating a ballooning litter problem on land and sea as global plastics production has risen to about 250 billion pounds annually.

    But will conversion to a plant-based substitute really solve everything? Considering a few key questions should help us ferret out some of the critical issues that would need to be addressed before we can give bioplastics a thumbs up or down.

    The Environmental Working Group reports that toxic fire retardants (PBDEs) are found in mother's milk.

    Plastics can pose threats to human health at all stages in our life cycles, with specific risks varying with the type of plastic.

    In the process of converting petroleum or natural gas into plastic, toxic chemicals can be released into the air and water supply. For example, vinyl chloride, a known carcinogen, is used to make polyvinyl chloride (PVC) plastics. A chemical called perfluorooctanaote (PFOA) used in the production of plastic-coated non-stick cookware is also carcinogenic.

    An assortment of “additives” is often needed to lend particular characteristics to a product. Many items, like computer casings and hair dryers, require flame retardants because plastics are highly flammable. Read the rest of this entry »
