Which part of the world is snakes heaven?

 The island Ilha de Queimada  in Brazil is inhabited completed by venomous snakes. There is exactly no predator for these snakes on the island which resulted in the tremendous increase in there population so it is assumed that on an average there are five snakes in one square meter area. The poisonous  snakes like The King cobra and vipers are found on this island. However, the deadliest snakes to be found there are the Golden Lancehead viper. According to statistics, about 90% of deaths resulting from snake bites in Brazil are caused due to bite from this snake. A single bite of this snake contains enough venom to kill two humans at a single time. Several tales have been associated with this snakes island. Mostly, the dense population of snakes has kept humans away from the island but according to those tales, a fisherman once wandered off the to the island, only to be bitten by one of the thousands venomous snakes of the area. He barely made it to his boat before giving up his life. The snakes venom causes the skin around the bite to melt away, making survival chances of the victim extremely slim. Human habitation is nil on the island. Only scientific persons after having granted permission to do so can visit the island. The snakes live mostly on migrating birds that stop on the island for rest. A plan to establish a banana plant on the island had been proposed at one point. However, for obvious reasons, it was never established.
