Considering the subject matter — the extinction or likely extinction of much of Earth’s biodiversity — Kolbert manages to write an absorbing narrative which wasn’t just depressing, though it sometimes was that, but also fascinating. She covers various creatures that we may have seen the last of, or may soon see the last of; creatures which only survive in captivity, and creatures which we didn’t even think to protect.
The fact is, humans are doing a lot of damage to our own ecosystems. Kolbert documents that and shows where it’s going, or at least, where it’s likely to go. What happens in the end is still, maybe, there for us to change. Maybe. It’s too late for a lot of species — perhaps most amphibians, for example — but we might still be able to stop this. The Sixth Extinction goes into some of the delights biodiversity has to offer, perhaps in hopes of inspiring some people to step up.
None of it came as a surprise to me, but I found the book interesting and entertaining all the same, if not exactly uplifting.
