BADLY BEHAVED VISITORS
4.1. Once, Mount Everest was unpolluted. Today, it is full of rubbish. Since 1953, over 6,000 climbers have reached the top of the mountain. Each climber produces on average 8 kg of rubbish. Today, climbers pay $4,000 before they set off and they get this back if they return with their rubbish. However, there are still a lot of old tents, oxygen tanks and food containers on the mountain from previous expeditions.
4.2. While not as bad as rubbish, stone towers that tourists make to photograph and share on social media damage the environment. Stones are homes for living things. Little insects live underneath them and some birds use them to make nests. In Tenerife, local people have put up posters to warn tourists against building stone towers. They hope this will be enough to conserve the beaches along the island's coast.
4.3. Meanwhile, the beaches in Sardinia are losing their sand. Local people say that tourists steal around six tonnes each year. Many beaches are now closing and tourists have to pay to visit others. There's a fine of up to €3,000 for taking sand and shells from Sardinia, but airport security is still finding them in people's luggage.
4.4. Damage doesn't just happen to natural sites. In 2017, an exhibit at the Hirshhorn Museum in Washington, DC. was damaged by a tourist taking a selfie. While the visitor was taking the photo, he fell backwards and broke a piece by Japanese artist Yayoi Kusama. The museum closed for three days as a result of the accident.
