8 holiday destinations at risk of being ruined by tourism

Tourism has affected this picture-perfect island so much that it is actually temporarily closed to tourists. The Filipino president announced in April that the island would be closed for six months after calling it a "cesspool" thanks to its poor sewage system, reports Time.

Officials reportedly said nearly 200 businesses (mainly aimed at tourism) were not connected to the island's sewage system and instead were dumping filthy water in the ocean.
