Sometimes people call ours a “throwaway society”. That means that we’re always throwing away old things and buying new ones. Many times, you no longer need something, but someone else may just need to buy one. For example, if your baby doesn’t like his toy car any longer, why not give it to a nearly family who has a little kid? That’s one less plastic toy car that they need to buy. It’s also one less plastic toy that needs to be produced, packaged and shipped to the toy store.

Here are some other ways to help save resources (资源)for the society:

★Use the other side of the paper.

★Use rechargeable (可再充电的) batteries for your electric toys, MP3 players, cell phones, and cameras.

★ Choose reusable travel cups instead of disposable (一次性的) paper or plastic cups.

★Take your own cloth shopping bags when you go shopping.

★ Drink tap water instead of buying bottled water.

And there are some things you can exchange with your friends, for example, books, toys, even clothes. It's a way for everyone to get something new without spending any money and without throwing many things away.
