Before you read Tom's essay on environmental problems, glance at the title and pictures and predict the main idea of the essay.
                                                       CLEAN UP YOUR BUTTS1 AND BAGS
      All sorts of items become litter, but two of the most common and most dangerous are cigarette butts and plastic bags. Litter is a big problem for our environment, but it is a problem that individuals can easily do something about. Not littering at all or cleaning up litter, such as cigarette butts and plastic bags, greatly improves the quality of our environment.
      Although cigarette butts are small, they are bad for the environment. Over 1,600 billion cigarettes 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 spoil2 the beauty of the environment, they contain some very toxic3 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. Because there are so many butts and because they can take up to 5 years to break down, the toxic chemicals add up to a large amount. So, if people have to smoke, they should not throw away the butts but put them in the rubbish bin4 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, ff they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous5 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 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 countless6 fish each year worldwide. When the animal dies and breaks down, the plastic bag can become free again to kill another animal. 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. The earth would be a better place because it would be less polluted. And we would know that we were doing something to look after our planet7. However, I believe the best solution would be not to
smoke or use plastic bags at all.
