Because traveling by plane causes air pollution, San Francisco International Airport offers passengers a way to reduce their guilt. Kiosks are provided that calculate the amount of carbon dioxide an individual’s trip will cause and the cost of offsetting it. After swiping their credit card, customers will get a receipt listing the specific carbon-reducing projects their money will be used for. However, because Delta Airlines has been offering customers an opportunity to charge certified carbon offsets on its Web site, Delta actually led this charge to clean up carbon footprints.
Liquid wood cleans up carbon footprints. Liquid wood is a bio-plastic developed by German researchers. It’s made from lignin, a usually discarded byproduct of papermaking, which is mixed with fibers from flax, hemp or wood, as well as wax. Liquid wood can be used to make everything from toys to car parts. Because it’s a strong, non-toxic alternative to crude-oil-based plastics, its price is unaffected by increases in crude oil prices and it’s free of the heavy metal and phthalate health concerns of plastics. Liquid wood is a promising, renewable, green alternative to plastic – available in colors other than green.
The White House might be greener because of the White House Organic Food Project, a grassroots campaign to have an organic garden on the White House lawn. Daniel Simon and Casey Gustowarow have driven an upside-down school bus fused to the top of another school bus through 25 states asking people to sign their petition. On top of their vehicle there’s a small vegetable garden to promote organic farming for healthy living, as well as for reducing the amount of fuel used to transport food. Organic farming at the White House is meant to inspire Americans to have organic gardens – but first the idea has to grow on President Obama.
Death Valley’s famous black skies for unspoiled stargazing are growing lighter. Although Las Vegas is 85 miles away, its light pollution – which increased 61% between 2001 and 2007 – makes the city appear brighter than the planet Venus. Theoretically one should be able to see 6,000 stars from Death Valley; but due to the Vegas neon, only about 2,500 are visible. To be the first dark-sky national park, Death Valley must shield or change two-thirds of its 700 light fixtures. As the park covers 3.3 million acres, park rangers are in the dark about how soon that can be accomplished.
