Why do we like drinking water from plastic bottles(塑料瓶)? Some people think it is healthy and clean. Others drink bottled water because it's easy - you can carry it around with you. In hot countries, like Greece, we often buy bottles of cold water in the summer.

However, making lots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source of energy. If we reduced the number of bottles we made, we wouldn't need so much oil. Plastic bottles also pollute the environment. If we reused all our plastic bottles, we wouldn't need so much space for rubbish dumps.But in Greece, we don't reuse much of the plastic we use. In 2006, Greeks reused only about 10% of plastic waste. The rest became rubbish on land and in rivers and seas.

So next time you want to throw away a plastic bottle in the litter bin, stop and think. If you reuse it, you would help the environment. But what can you do when there isn't a bin near you? Well, there are lots of useful ways that you can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut a bottle in half, you will have a plant pot. Go green! You can make a difference.
