The cars we use all over the world are detrimental to our Earth’s environment. In the United States, air quality often fails to meet federal standards. Air pollution, water pollution, global warming, and ozone depletion are some of the problems we face each day that reflect the consequences of our actions. The cars we drive emit exhaust gas, whose harmful elements cause acid rain and global warming. As a result of growing environmental concerns, the US government has been trying to resolve these problems. One such solution is the Hybrid car, which can save resources by giving off less emission. However, among the many benefits of Hybrid cars, there are also some drawbacks as well. Hybrids still exhaust some emissions, and their large batteries require frequent replacement. Now, fortunately, many companies are thinking of ways to improve Hybrid cars because if we don‘t stop driving gasoline powered vehicles, the earth’s resources will be destroyed.

Driving a car is the worst pollutant. Despite attempts to make engines more fuel efficient and the increase in antipollution devices, emissions from passenger vehicles are increasing in Canada and the US. The main cause of this problem is that cars are getting bigger and consumers are driving pick-up trucks and sports vehicles instead of smaller, lighter passenger vehicles. The average new car in 2001 consumed more fuel than the average car in 1988. In 1987 cars averaged 25.9 miles to the gallon in the US. Fuel efficiency plunged to 24.6 miles/gallon by 1998 and continues to drop as larger vehicles replace smaller ones.

Exhaust from all combustion engines combine to produce harmful effects on people and the environment. The burning of fossil fuels from the unlimited use of vehicles has turned cities into huge deposits of toxic chemicals. The major car pollutants are carbon monoxide, hydrocarbons, nitrous oxides,
