Biodiversity's a good thing

http://green.blogs.nytimes.com/2010/12/02/as-biodiversity-declines-disease-flourishes/ This is one of the best articles I've read on biodiversity. In short, the less genetic diversity in a crop or herd, the greater the risk disease will decimate it. If nothing else, the article will give you a greater appreciation for the opossum. It turns out the opossum, reviled by many for its rat-like tail, plays a big role in controlling the ticks that spread Lyme Disease.
