We hear a great deal about how the encroachment of humans is driving many species to extinction. What we hear much less about is extinction at the sharp end, on a case-by-case basis. Here Tom Lathan presents ten case histories of species that have become extinct very recently, that is, in the 21st century, their demise known to the very day. The only one anyone is likely to have heard of is Lonesome George, the last Pinta Island giant tortoise of the Galapagos. Others include birds, bats, fish, snails, and a shrub. The time, energy of efforts expended by conservationists to keep the various species alive in the face of natural disasters and bureaucratic ineptitude add up to a poignant read, but in the end I was left waiting for the other shoe to drop. All the species lived on small islands or in remote, patchy habitat and would very likely have gone extinct anyway, and rather soon, whatever anyone did. Some were close relatives or even variants of other, known species, so their existence and extinction rather depended on one's viewpoint as a taxonomist. Lathan didn't broaden his outlook to, say, consider other threatened species that represent much deeper lineages: the tuatara, say, or the aye-aye. More importantly, he didn't explore whether the extinction of a few species of which nobody had heard might be the thin end of the wedge. That once one starts to pull at the seemingly insignificant threads of an ecosystem, first one species goes, and then another, until the whole thing collapses. And he doesn't address the perhaps unfashionable view that, by creating new and novel patches of habitat, and moving animals and plants around, human activity might actually have increased biological diversity. In which case the efforts of conservationists to save endangered endemics, while laudable in and of themselves, look increasingly like Canute trying to stem the tide on command. Nature is much bigger than humanity, against which the efforts of humans to demand that nature stays exactly as it is looks a lot like hubris.
