According to Nicholas Kristof's column in today's New York Times, the real story that no one is dealing with, beyond Darfur, global warming in general, and our love of oil, is that the change of temperature is making the sea more acidic. Apparently, this will change the ability of the smallest forms of life, such as plankton, to reproduce, and thus affect the food chain, all the way up to the big whales and, yes, the fish we eat.

So, can we just say it now? Stop eating fish. Just stop. No more, "What's wrong with fish?" or "Are mussels or clams sentient?" I mean, c'mon. Leave them alone. Unless you happen to be a Madagascan living on the coast with no other sources of protein to hand or mouth, you really don't need to touch the oceans. Let's leave the fish for those who really need them: in other words, other sea creatures. Given that in fifty years the seas may be expanses of nothing, we need to give as much chance to the creatures of the deep as we can.
