First Para. Point of view

Second Para.

First point of the argument

Evidence

Cigarette buts and plastic bags are a serious environmental problem.

Butts are small but are still bad for the environment.

1.1600 billion cigarettes are smoked each year in China. Many of these become litter.

2. 4.5 trillion butts are littered every year in the world.

3. Butts are ugly.4. 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.

Third Para.

Second point of the argument

Evidence

Plastic bags are a danger to the environment.

1.Plastic bags are made from non-renewable resources. If they are not recycled, these resources are lost to us.

2.In china, 2 billion plastic bags are used every day.

3.Plastic bags last from 20 to 1,000 years in the environment.

……Fourth Para.

The Environmental Effects of Fossil Fuels

There is no doubt that fossil fuels bring a lot of

good to us. But do you know that many of the

environmental problems our country faces today

result from our fossil fuel dependence.

The environment faces air pollution, global

warming, acid rain, and several other very serious

problems because of our use of fossil fuels. Over

the last 150 years, burning of fossil fuels has

resulted in more than 25 percent

A sample version

increase in carbon dioxide in our atmosphere. Carbon dioxide is one of the main factors in global warming which is negatively affecting everyone. Fossil fuels also affect water pollution, land pollution, and thermal pollution (heat pollution). Coal mining is one of the causes of pollution in the environment. After the mining is completed, the land will remain barren.

Materials other than coal are also brought to the surface in the coal mining process, and these are left as solid wastes.The production, transportation, and use of fossil fuels are to blame for the effects of pollution on the environment. Then what should we do? We should spare no effort to improve our environment. Please save energy and use fewer fossil fuels in our daily lives.
