If you want to protect wildlife in developing countries, the conventional wisdom has long been that you put the animals in a well-run reserve and safeguard it like it were a prison, keeping the wildlife separate from the people who actually live there. The locals, in this case, are the threat because they're the ones who poach endangered wildlife, whether for the ivory or skin trade, or just for meat. But, so far, this conventional wisdom hasn't led to much progress. According to the International Union for Conservation of Nature's annual report, nearly 40% of surveyed species are currently threatened, and their numbers are growing.
