Single-use plastic is a big problem, damaging the environment, killing marine life, breaking down into micro-pellets that are even found in the human blood stream. But our individual efforts to wean ourselves from plastic is insufficient unless we attack the problem systemically. Christy Walters owns one of our local eco-friendly stores, Reuse Revolution, which sells plastic-free housewares, personal grooming products and refills of detergents and lotions. She also writes an excellent monthly newsletter on environmental issues. (You can subscribe at the bottom of the website.)
