Matt: The article you linked is simplistic at best, and the dumbest thing I've ever read at worst. First, their measure of "better for the environment" is extremely narrow - the study measures carbon emissions but says nothing about waste. The carbon emissions finding is insightful, for sure, and should make people think twice before they reflexively assume a "reusable" bag has no impact. But the article says nothing about plastic bags ending up in landfills or waterways. Does that not impact the environment? The DC bag tax, which I assume you don't support, wasn't created as a high-minded local solution to global warming... they did it to keep plastic bags from ending up in the Anacostia River. Alternatively, have you ever heard of the Great Pacific Garbage Patch?
Despite the scorn with which you and the author to this article refer to the "environmentalist crowd," you've taken a simplistic study and used it to justify a wasteful status quo and then beat your chest about it. The biggest problem with plastic bags isn't that they exist, it's that they are overused and then wasted. The best thing anyone can do for the environment is use less, and in a country that values thrift when it comes to our economic decisions, I've never understood why some people look down on the idea that we shouldn't waste our other resources.
