Answer key for Exercise 2 (P67)Litter is a serious environmental problem
Point of view
Cigarette butts are small but are still bad for the environment. 1. Over 1,600 billion cigarettes are smoked each year in China. Many of the butts become litter.
First point of the argument;
2. 4.5 trillion butts are littered every year in the world.3. Butts spoil the beauty of the environment4. Butts contain toxic chemicals. These get into the water supply. These decrease the quality of the water and endanger living things.5. Butts take up to 5 years to break down, so the toxic chemicals add up to a great amount.
Plastic bags are a danger to the environment.
Second point of the argument
Plastic bags are made from non-renewable resources. If they are not recycled, these resources are lost to us.In China, 2 billion plastic bags are used every day. Many of these become litter.
3. Plastic bags last from 20 to 1000 years in the environment.4. They can travel long distances in the air and water. They are in rivers, parks, beaches and oceans. 5. Plastic bags kill up to one million seabirds, 100,000 sea mammals and countless fish each year worldwide.
6. After the animal breaks down, the plastic bag becomes free and can kill another animal.
The environment would be less polluted if we cleaned up cigarette butts and plastic bags. The best solution would be not to smoke or use plastic bags at all.
