A Wave of Green Hits Surfing Industry
by Sarah S. Mosko, Ph.D.

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.

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
By Sarah S. Mosko, Ph.D.

California Certified Farmers' Markets are "the real thing," places where 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 »

Firefighters Back Banning Controversial Flame Retardant

Sarah S. Mosko, Ph.D.

BFRs are so ubiquitous that they are found in remote areas of the Artic and throughout the food chain, from zooplankton to dolphins and polar bears.

BFRs are so ubiquitous that they are found in remote areas of the Artic and throughout the food chain, from zooplankton to dolphins and polar bears.

Your TV, mattress, couch and computer could be sources of man-made toxic chemicals building up in human tissues, including breast milk. Sounds crazy, but it’s not.

Many consumer products are imbued with a class of flame retardants considered by many to be bad news since they accumulate in fatty tissues, resist breakdown in the environment, and disrupt normal development in lab animals. They are called polybrominated diphenyl ethers or just brominated flame retardants (BFRs).

Introduced in the 1970’s, BFRs have become commonplace in upholstery foam, textiles and electronics because synthetic materials, like petroleum-based plastics, are generally more flammable. BFRs impede the spread of fire bycreating a layer of bromine gas around a heated product, keeping oxygen at bay. They comprise up to 30% of an item’s weight and migrate out over time into air, dust, and soil. Read the rest of this entry »

The Polystyrene Ban Wagon
Laguna Beach will require biodegradable eating utensils
by Sarah S. Mosko Ph.D.

polystyrene

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 Laguna Beach regulation follows on the heels of similar bans enacted recently in Santa Monica, Calabasas, and Malibu and applies to private food vendors as well as city-sponsored events and Read the rest of this entry »
