CAR IS AN ECOLOGICAL DISASTER.

1. According to the United States Environmental Protection Agency, driving a car is the single most polluting thing that most of us do. This is not a new problem. In the 1950’s the Los Angeles smog made headline news. Car exhaust causes health problems. There are many solutions to the problem.

2. Laws were enacted as long as 20 years ago to control pollution caused by cars. Since then laws have been made, such as special nozzles on gas pumps that prevent vapor from getting into air. We also have more tests on cars to make sure cars are maintained in a way that protects our environment. In cities, laws ask that more people ride on buses, and employees that drive company cars should limit the time they drive and the number of trips that they make.

3. Cars emit several pollutants that are toxic. This causes many problems. One problem it causes is cancer. Most cars generate hydrocarbons, nitrogen oxides, and carbon monoxide. Hydrocarbons cause eye irritation, coughing, wheezing, shortness of breath, and lung damage. Nitrogen oxide causes acid rain and leads to water quality problems. Carbon monoxide prevents oxygen from going through the lungs properly. All of these problems can be serious and effect the health of the people who live in the United States.

4. Some solutions to the problem are: cutting down on the number of cars, traveling at steady speeds, and keeping your car in good shape. You should never over fill your gas tank. You should always use clean gas. People should buy newer cars because they are made to create less pollution.

5. In summary, the problem of pollution from car exhaust is not new. The situation is so serious that many laws have been enacted to protect our environment. The pollutants that are emitted in car exhaust are very dangerous to our health. There are solutions to the problem if we just pay attention.
