All of us live in one world．While we are eating food， drinking water，wearing clothes，watching TV，using computers and so on， we are producing waste every moment．When we finish reading a newspaper，the paper will become waste．When TV sets or computers are broken， they will become electronic waste．

Plastic bags are often used in our everyday life．The number of used plastic bags is increasing day by day．We like to use plastic bags because they are convenient．When we get home，we throw the plastics away．These are called "white pollution"as most plastics are white．Rubber is also common in our daily life．Many of our products are made of rubber， just like the tyres （轮胎） and the bottom part of our shoes．It's true that rubber plays an important role in our life．However， it also brings us some trouble when it has been used for a long time．The old rubber pollutes environment very badly because it can't break downeasily in nature﹣it will stay unchanged for a long time．This is really a big problem all over the world．

Everyone should play a part in saving our world．For example， when we go shopping， we can bring cloth bags instead of plastic ones．And we should do something to recycle rubber．Our small actions can make a difference and lead to a better future．
