It's very important that we all recycle(再次利用). In nature, everything1again. For example, when an animal dies, it becomes2animal's food. Nothing is wasted. But humans have created things like plastic bags3can't be broken down by nature. Our rubbish kills animals and4water and soil.5we continue making too much rubbish, the problem will only get worse. If nature can't reuse the rubbish, we must recycle6. We should clean up the rubbish we've made because nature can't.
Recycling is also the right thing to do for another reason. The earth is rich in natural materials like water and trees,7these materials are not endless. We use up our Recycled natural materials much8than the earth is able to reproduce them. For example, each year we cut9more than 6,000 square miles of forest. But it takes an average of 25 years for a new tree10.
Recycling can help us save the earth, so let's take action right now.
Why do we like drinking water from plastic bottles? Some people think it is healthy and clean. Others drink bottled water because it's easy- you can carry it around with you. In some countries, like Greece, we often buy bottles of cold water in 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(来源) 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 recycled all our plastic bottles, we wouldn't need so much space for rubbish dumps. But in Greece, we don't recycle much of the plastic we use. In 2006, Greeks recycled 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 recycled it, you would help the environment. But what can you do when there isn't a recycling bin near you? Well, there are lots of useful ways that can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut in half, you will have a plant pot. Go green! You can make a difference.
