Tourism is both a blessing and a curse. While a healthy amount can improve the economy, too much of it can be harmful to the environment and local populations.
Maya Beach, Thailand
As more and more tourists flooded into the sandy shores, Maya Beach became impossible to enjoy; visitors could hardly walk, not to mention lie down. Thailand was forced to close the beach for months in 2018. Though the closure was only supposed to be temporary, it is now shut down indefinitely.
Boracay, Philippines
The beautiful island of Boracay once was respected for its exclusivity (独特性). But in recent years, massmarket tourism and lack of the basic facilities have led to a major downfall. The island underwent a sixmonth closure to visitors in 2018 to allow authorities to restore it. Under the new rules, a maximum of 19, 200 tourists are allowed on the island at any one time.
Machu Picchu, Peru
Machu Picchu is being affected by too many people visiting at the same time. To prevent the masses from damaging the site, tourism authorities are trying to introduce strict visiting time, advance ticket purchases, and visitor limits.
Cozumel, Mexico
The island of Cozumel has become a popular tourist spot. Many visitors arrive by ship, which has harmed one of the island's most prized possessions: coral reefs. Marine (海洋的) biologist German Mendez has started an organization to protect the reefs.
