In human-free zones, Wilson believes, many endangered species would recover and their extinction would, most likely, be averted.
If it makes you feel any better, nobody treated the northern population as a distinct species prior to a few years ago, while the southern population is a conservation success story. From being presumed extinct in the late nineteenth century there are now more 20,000 of them - the most populous of living rhino species.
