The highest challenge is the huge amount of waste that has to be disposed, such as raw sewage and garbage generated by 24 million international tourists, as well as 69 million national tourists throughout the year (2013). It also means damage to local ecosystems, especially those which are fragile or easily disturbed by the presence of humans, such as mangle forests, jungles and coral reefs. As many tourists enjoy a "living souvenir", many of them try to take away exotic species which more often than not, are threatened or outright endangered. Finally, to leverage the economic benefit of the tourism industry, many local governments allow new construction projects which usually have an environmental impact on their own, such as opening a new hotel complex close to a turtle nest, or draining a mangle forest to build a new highway.
