In Philippines, south of Manila, there is a popular island resort known as Boracay. The famous destination is popular among holiday seekers and attract up to 2 million visitors a year, bring in more than a billion dollars worth in tourism tickets. The beach and clear sea water as well as a hosts of top hotels and resorts were ranked highly in Asian top destinations.
However, this proved to be its downfall. As it became more and more popular, flooded with tourists all over the way to the beach, the island is now heavily polluted. The problem is mainly blamed on the local government for failure to enforce marine conservation, garbage and sanitation.
Business like hotels and resorts are dumping their waste into local canals which primary purpose is to collect rainwater and irrigation. These illegal dumping are causing serious sewage problems and the island is now full of dumps and garbage. These resulted in low hygiene and high contamination of usable water.
Earlier this year, the Philippines President Rodrigo Duterte had enough of it and ordered a 6 months closure of the whole island to fix sewage and environment-related problems. The president is calling Boracay a "cesspool". "You go into the water, it's smelly. Smells of what? Sh*t," he had said.
Boracay, among many other popular destinations around the world, is being ruined due to its popularity. Much education need to be imparted to tourists and local businesses to be responsible in maintaining the local resources for a continuous growth.
