It seems that we have almost unlimited means for adversely affecting our natural environment. The latest is effects of prescription drugs in the sewage system (registration required). Examples include birth control hormones causing bizarre sexual development in fish, and Prozac killing tadpoles and disorienting the survivors. I'm not surprised as much that these drugs would be harmful to other species as I am that such quantities seem to pass through our systems intact. I guess we're going to have to think even more about how we treat our physical wastes; saving money won't seem so smart when we run out of fish, let alone start filling our drinking water with other people's prescriptions!
