On the heels of our reporting about Canada's probable move to ban BPA plastics comes a story about researchers working at Missouri University of Science and Technology to develop hybrid plastics that would biodegrade in landfills within four months. As our editor Nicole Dyer pointed out in a comment to the BPA post, the larger and more important issue facing plastics is their propensity to stick around forever.

Seattle is poised to join the ranks of San Francisco and Ireland by imposing restrictions on the use of disposable shopping bags. The City Council vote on the proposal—expected to pass by a wide margin—will occur this summer and would take effect at the start of 2009. While Ireland and San Francisco have banned plastic bags outright, Seattle's proposal will instead impose a twenty-cent fee on every paper or plastic bag used by consumers at the point of sale. (The proposal also bans styrofoam food containers.)
