Some years ago, I started avoiding Teflon-coated cookware after hearing that the nonstick chemicals, while awfully convenient for cooking, are awful for human health. They're called perfluorinated compounds (PFCs), and it turns out that they're awful for the environment, too (especially if you're this species of turtle, or a pet bird).
So today, when I got an email from the Environmental Working Group informing me that PFCs are used in various types of grease-resistant food packaging (for things like microwavable popcorn, fast food, and pizza)—and that Gov. Arnold Schwarzenegger is threatening to veto a bill in the California state legislature that would ban the use of PFCs in food packaging—I did the email's bidding, calling the gov and signing the petition. If you'd like to do the same, click here.
To me, the most irksome thing this battle has revealed is the fact that we have no way of knowing which specific packages contain PFCs. As this page from the Environmental Working Group's site puts it, "consumers are unfairly deprived of their essential right to know and to make informed, independent decisions.... [A] consumer going to the store would not know which brands to avoid because manufacturers are conveniently withholding this crucial information."
How about some legislation requiring transparency in this arena?
