The Yellow Mountain is a place of great interests①. There are lots of tourists seeing sights everyday②.

Years ago, many tourists paid no attention to environment protection. They littered everywhere, throwing waste paper, plastic bags and tins all of③the place. Besides this, they killed animals, caught birds, dug up trees and pick④flowers. What’s more, they often made a fire cook⑤in the forest. That was dangerous.

Great changes have been taken place⑥here. Now when tourists leave, they take away their rubbish with them. They no long⑦h(yuǎn)urt animals. Plants are also well protected. All the tourists carry their own lunch in order not to start forest fires. We must be thankful for their good deeds.
