If you know where to find a good plastic-free shampoo, can you tell Jeanne Haegele? Last September, the 28-year-old Chicago resident resolved to cut plastics out of her life. The marketing coordinator was concerned about what the chemicals leaching out of some common types of plastic might be doing to her body. She was also worried about the damage all the plastic refuse was doing to the environment. So she hopped on her bike and rode to the nearest grocery store to see what she could find that didnt include plastic. I went in and barely bought anything, Haegele says. She did purchase some canned food and a carton of milk--only to discover later that both containers were lined with plastic resin. Plastic, she says, just seemed like it was in everything.
Shes right. Back when Dustin Hoffman received the most famous one-word piece of career advice in cinema history, plastic was well on its way to becoming a staple of American life. The U.S. produced 28 million tons of plastic waste in 2005--27 million tons of which ended up in landfills. Our food and water come wrapped in plastic. Its used in our phones and our computers, the cars we drive and the planes we ride in. But the infinitely adaptable substance has its dark side. Environmentalists fret about the petroleum needed to make it. Parents worry about the possibility of toxic chemicals making their way from household plastic into childrens bloodstreams. Which means Haegele isnt the only person trying to cut plastic out of her life--she isnt even the only one blogging about this kind of endeavor. But those whove tried know its far from easy to go plastic-free. These things are so ubiquitous that it is practically impossible to avoid coming into contact with them, says Frederick vom Saal, a biologist at the University of Missouri。
