The End of Species Extinction, by Jeffrey Sachs

Jeffrey Sachs believes that we humans have a major self-control problem, and that we are absent-minded, negligent, aggressive killers. We are driving species to extinction. After diagnosing the (moral) disease Sachs hands out the cure - "for a very low cash outlay" we can create marine reserves, pay fishermen to stop "bottom trawling," pay farmers to stop clearing forest and slow human-induced climate change. And there you go - planet saved.
