Although cigarette butts, are small, they are bad for the environment. Over 1,600 billion cigarette are smoked each year in China and large quantities of the butts are thrown away. Worldwide, about 4. 5 trillion butts are littered every year. Apart from the fact that butts spoil the beauty of the environment, they contain some very toxic chemicals. These find their way into the water supply where they

　　decrease the quality of the water and endanger plants and animals that live there. So, if people have to smoke, they shouldn't throw away the butts but put them in the rubbish bin instead.

　　Plastic bags are another common form of litter that is a danger to the environment. There are several reasons for this. They are made from oil and gas, which are non—renewable resources. If they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous number of these become litter. This is a huge problem because they last from 20 to 1,000 years in the environment. They float easily in the air and water and travel long distances. They find their way to rivers, parks, beaches and oceans. Plastic bags kill up to one million seabirds, 100, 000 sea mammals and countless fish each year worldwide. It is up to people not to let plastic bags become litter. It would be better if they used fewer and recycled them.

　　Cleaning up your cigarette butts and plastic bags would improve the environment. And we would know that we were doing something to look after our planet. However, I believe the best solution would be not to smoke or use plastic bags at all.
