Worldwide, the largest and most charismatic animals, the last of the megafauna, our most ecologically important predators and big ungulates, the wildest wild things, will be the first to go in the anthropogenic extinction event of the Holocene Era. The tiger and leopard and the elephant and lion in Africa and Asia. The primates, the great apes, our wild cousins. The polar bears in the Arctic Sea. The shark and killer whale in every ocean. “Extinction is now proceeding thousands of times faster than the production of new species,” biologist E.O. Wilson writes. Between 30 and 50 percent of all known species are expected to go extinct by 2050, if current trends hold. There are five other mass extinction events in the geologic record, stretching back 500 million years. But none were the result of a single species’ overreach.
