In colonial india, the british put a bounty on cobras. Indian villagers who would have usually just killed the cobras and went on with their day now tried to catch them alive so they could then farm them for multiple bounties. This ballooned the snake populations to ridiculous levels, and then the british found out about the scheme. They then cancelled the bounty program, and the snake rearers released their animals on places they thought were far from people.

Net result: More snakes than ever before.
