Реферат: Car Is An Ecological Disaster
“According to the United StatesEnvironmental Protection Agency, driving a car is the single most pollutingthing that most of us do.” This is not a new problem. In the 1950’s the LosAngeles smog made head-line news. Car exhaust causes health problems. Thereare many solutions to the problem.
Lawswere enacted as long as twenty years ago to control pollution caused by cars. Since then laws have been made, such as special nozzles on gas pumps thatprevent vapor from getting into the air. We also have more tests on cars tomake sure cars are maintained in a way that protects our environment. Incities, laws ask that more people ride on buses, and employees that drive companycars should limit the time they drive and the number of trips that they make.
Cars emit several pollutants that aretoxic. This causes many problems. One problem it causes is cancer. Most carsgenerate hydrocarbons, nitrogen oxides, and carbon monoxide. Hydrocarbonscause eye irritation, coughing, wheezing, shortness of breath, and lungdamage. Nitrogen oxide causes acid rain and leads to water quality problems. Carbon monoxide prevents oxygen from going through the lungs properly. All ofthese problems can be serious and effect the health of the people who live inthe United States.
Some solutions to the problem are: cuttingdown on the number of cars, traveling at steady speeds, and keeping your car ingood shape. You should never over fill your gas tank. You should always useclean gas. People should buy newer cars because they are made to create lesspollution.
In summary, the problem of pollution fromcar exhaust is not new and is the single most polluting thing we do. Thesituation is so serious that many laws have been enacted to protect ourenvironment. The pollutants that are emitted in car exhaust are very dangerousto our health. There are solutions to the problem if we just pay attention.Alexander V. Myskin, gr. 301
