Clark's executive producer Christa recently gave him an article from Health magazine that spoke about how plastic water bottles can leach Bisphenol-A (BPA), a chemical that's toxic in lab rats. So the inevitable question arises: Can it also harm us? Clark's not buying the leaching plastics theory, but he thinks you shouldn't drink bottled water because it will drain your wallet. Most bottled water comes from the tap, including Aquafina and Dasani. Just compare the numbers for yourself: Drinking tap water will cost you 40 cents/year vs. $1,500/year for bottled water, according to one study. Then there's the environmental angle: Between transportation, packaging and disposal, bottled water is an eco-disaster. If you're still reluctant to drink from the tap, try using an affordable filter. The Brita system was recently featured on NBC's The Biggest Loser -- a show that's watched by both Christa and Clark's other producer Kim.
