Whether or not you believe that global warming will lead to there being some choice beach-front property available on the western slope of the rockies within our lifetime, you can't deny that one of the biggest challenges facing our environment is waste. We humans produce a lot of trash, and unless we want this planet to become one big landfill, we need to hold ourselves responsible for doing something about it. Of course, we should all do our part to recycle as much as possible, but what about repurposing? The website, greenupgrader.com, has dozens of imaginative—and very cool—ways to extend the lives of otherwise "disposable" objects. For example, the strangely chic zippered container created from two 2-liter pop bottles, or the Thai Buddhist temple created entirely from beer bottles (images below). Have a look at the site. You just may be inspired to look at your trash a little differently.
