POLLUTION

THESIS STATEMENT: Air pollution is a current problem in the whole world. It has been a problem for many years, and now it is increasing even more.

               I.     Pollutants and causes.

A.    Carbon and nitrogen dioxides.

1.) Produced by vehicles.

2.) Produced by heating machines at homes.
3.) Produced by pesticides.
4.) Produced by burning fossil fuels.

B.     Fossil fuels.

1.) Burned by factories and industries.

2.) Used and burned for heating machines.
3.) Burned to produce electricity.

C.     Use of cars and other motor vehicles.

1.)  Carbon dioxide emissions from the exhaust fumes.
2.)Necessary for daily life.

              II.     Effects on human health.

A.    Respiration problems.

1.) Lungs.

2.) To breathe because we breathe polluted air.

B.     Heart problems.

1.)  Blood.

              III.     Effects on the environment.

A.    Increase of the Greenhouse effect.

B.     Increase of global warming.

C.     Decrease of the Ozone layer.

              IV.     Solutions.

A.    Use public transport to reduce the emissions of carbon dioxide.

1.) Promote the use of pooling cars (in order to reduce the number of cars in use).

2.) People must not use cars (NOT often an accepted solution).

B.     Switch off lights when going out in order to reduce the amount of fossil fuels burned.

1.) Fossil fuels produce electricity.

2.) Save environment from degradation.

C. Decrease the use of heating machines at homes.
1.) Less fossil fuels burnt.

CONCLUSION: Although finishing with pollution is a very difficult objective, the earth would be cleaner and less polluted if we carry out these easy steps and measures in our daily life, and the world will thank us.
