Here’s a half hour Fresh Air interview with Elizabeth Kolbert, who wrote the book The Sixth Extinction. Her descriptions of ocean acidification and amphibian extinction are particularly eye-opening. The whole thing is worth a listen (better to listen than try to read this transcript), but I especially liked this exchange:

GROSS: So this is going to sound like a horrible question, but, you know, I don’t get to see barrier reefs. I don’t get to see coral. I live in the city. What impact does it have on my life if coral reefs can’t grow anymore and if they start declining because of the acidification of the oceans?

KOLBERT: Well, I guess I’d give you two answers. The first answer is, you know, we are effectively undoing, you know, the beauty and the variety and the richness of the world, which has taken tens of millions of years to reach this point. We’re sort of unraveling that. And if that is something that you just say, well, I don’t care about, then I guess I’d say, well, what do you care about?

(LAUGHTER)

KOLBERT: But on another, on a more, you know, personal sort of like, OK, I want to know how – you know, what’s it mean to me, I guess my answer would be we’re not sure. You know, no one’s – we haven’t done this before. You don’t get to sort of see this experiment run over and over again. So we’re doing, it’s often said, a massive experiment on the planet, and we really don’t know what the end point’s going to be.
