Sadly, in our 'so long and thanks for all the fish' department, the world has lost another mammal due to development. China's nearly blind river dolphin, the baiji is now considered "functionally extinct." At the New York Times:

For the Chinese, I think that losing a half-blind river dolphin and a couple of oversize fish was a fair trade for all the money that is being made there now. China is an economic model envied by most of the rest of the world, and I think that many other (especially third world) countries will be confronted with similar decisions of economic development versus conservation of habitats and animals, and the response will be the same. From now on we will have to choose which animals will be allowed to live on the planet with us, and baiji got cut in the first round. It is a sad day. I know it is their country, but the planet belongs to all of us. We came to say goodbye to baiji, but after its being in the river for 20 million years, we apparently missed it by two years.

Sorry if I got a little emotional here, but the disappearance of an entire family of mammals is an inestimable loss for China and for the world. I think this is a big deal and possibly a turning point for the history of our planet. We are bulldozing the Garden of Eden, and the first large animal has fallen.
