Have you ever stayed in a hotel? Most Chinese hotels often provide guests with things like disposable (一次性的) toothbrushes, toothpaste, shampoo and slippers. Many guests like the idea because they don't have to bring their own. But, if you travel to Beijing, remember to bring your own things. Starting from June, some hotels in Beijing will no longer provide guests with these disposables. They want to ask people to use less disposable things.

Many disposable things are made of plastic(塑料). People throw them away after only using them once. It is a waste of natural resources and is very bad for the environment. Do you know, one Chinese person makes as much as 400kg of waste a year! Most of that waste comes from disposable things. In Beijing, people throw away about 19,000 tons of plastic bags and 1,320 tons of plastic lunch bowls every year! Plastic can take between 100 and 400 years to break down. So the less plastic we throw out, the better. So, wherever you travel, bring your own things and use them again and again.

Back at home and school, you can also do something to make our world a better place. Try to do these things in your daily life:

Use cloth shopping bags, not plastic ones.

After using a plastic bag, wash it out and let it dry. Then you can use it over and over again.

Do not use paper cups. At your school canteen(食堂), use your own bowl and chopsticks instead of disposable ones.
