Free monkey/empty trap
Everyone loves the adorable vervet monkeys of Nevis -- except for every single Nevisian ever. The microscopic West Indian island is beset by the furry imps, who have decimated the struggling farming industry. Mangoes, papaya, bananas, yams: The Caribbean climate is perfect for a number of valuable crops, but invariably the mischievous beasts get to the fruits and vegetables before they can be harvested.
In a sense they're another a lingering insult from slavery, having come over on slave ships from West Africa four centuries ago. Traps like the one above only catch the least clever of the creatures, now said to outnumber humans on the 36-square-mile island.
