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 these things of your own. That's because some hotels in Beijing have no longer provided guests with these disposables. Many disposable things are made of plastic. People throw them away after only using them once. It's a waste of natural resources（资源）and is very bad for the environment.

In Beijing, people throw away about 19,000 tons of plastic bags and l,320 tons of lunch bowls every year! Plastic can take 100 to 400 years to break down. So the less plastic we throw away, the better environment we will have.

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 use it over and over again.

Do not use paper cups.

At your school canteen（餐厅）, use your own bowls and chopsticks instead of disposable ones.
