Bottled Water Backlash
Bottled water is out, and tap water is in, says the May/June 2008 cover story of E – The Environmental Magazine (now posted at: www.emagazine.com). Call it reverse snob appeal. These days, it’s the tap water enthusiasts, concerned about the environment, who get to act self-righteous. Just like it has become cool to bring your own cloth bags to the grocery store and your own mug to the coffee shop, the reusable water bottle is the hip, new eco-accessory.

Urban Parrot Colonies
At least three dozen different parrot species are now considered threatened or endangered in their quickly shrinking native tropical and sub-tropical habitats (mostly in South America). As such, the health of wild flocks in the U.S. and other developed countries around the world may well be key to preserving these birds that could otherwise go extinct.

Recycling Old Clothes
The typical U.S. city with 50,000 residents has to pay (with local tax dollars) for the handling and disposal of some 3,000 tons of textiles every year. The shame of such waste is that textiles are so easy to recycle or otherwise find new uses for.

How much of an effect, if any, does the carbon dioxide in carbonated beverages have on global warming?
A typical 12-ounce can of soda contains up to six grams (.013 pounds) of carbon dioxide (CO2) gas, which either escapes into the atmosphere from the liquid upon opening, or from your body after you consume the contents. So yes, drinking carbonated beverages does contribute to your “carbon footprint,” but only ever so slightly.
