Smart Cars for Clean Air

Cars take us to school, work, and anywhere else we want to

go. We rely on cars to get us to a wide variety of places…and fast!

There is no doubt that the automobile has made our lives easier in

a number of ways. But there is also no doubt that cars are slowly

killing our planet. It is clearly time to rethink how we use cars in

our daily lives.

While cars have given us the convenience of easy travel, the

pollution they cause is a serious consequence. The Environmental

Protection Agency, or EPA, says that gas-powered vehicles such as

cars, trucks, and bulldozers are the main cause of air pollution in

large cities in the United States. In fact, they cause air pollution

throughout the entire world. Environmentalists have talked about

the dangerous effects of air pollution for decades. One way to stop

this pollution is to buy hybrids, or cars that run on both gasoline

and electricity.

Vehicles are responsible for air pollution because they run on

gasoline, a fossil fuel. When this fuel is burned in the process of

running a car, pollutants are released into the air. As long ago as the

1900s, some experts said that burning gasoline in automobiles could

damage the environment. Studies show that we are now paying the

price with our quality of air today. Those experts were right!

Hybrid vehicles currently coexist with gas-powered cars.

Hybrids could significantly reduce the pollution we release into

the air. It is true that these cars still use gasoline, but they certainly

use a lot less of it. Hybrid cars utilize a combination of gasoline and

electricity. One specific type of hybrid is a particularly good choice.

This is because this type relies mostly on electric power. An electric

motor turns the car’s wheels, and gasoline is used to generate the

electricity. The car is recharged by plugging it into an electrical outlet.

If everyone were required to drive a hybrid car such as this

one, the amount of pollution from the use of gas would be hugely

reduced. The government could make it a precondition that all new

car owners buy hybrids. We would also be conserving our fossil

fuels for other machines or necessary uses.

Hybrid cars have other advantages, too. Since they use

gasoline, they can be refueled at any gas station so that the driver is

not left stranded if there is nowhere to charge the battery. They are a

great choice because they do not require a huge lifestyle change for

drivers. They are very similar to the gas-powered cars that we are so

familiar with. They just have one major difference: they greatly

improve the environment in which we live.

Hybrid cars are the best choice to reduce air pollution around

the world. Transcontinental car manufacturers should be required to

stop selling the gas-guzzling cars of yesterday. Instead, they should

sell hybrids at reasonable prices so that all people will be able to buy

them. The future of our planet is at stake!

Fewer Cars for Clean Air

Cars are a major part of most of our lives. In many areas, people

count on their cars to do the things they need to do every day. But

there is a downside to having so many cars on the road. As gasoline is

burned, it releases dangerous pollution and harmful greenhouse gases

into the air. These gases get trapped in our atmosphere and increase

the overall temperature of Earth. As the planet’s temperature goes up,

ice melts and ocean levels rise. This can create dangerous international

problems for many people who live on coastlines. Rising temperatures

also affect people, animals, and plants around the world.

The intake of polluted air can be harmful to people. If people

were to burn less gasoline, there would be fewer carbon emissions

from our cars. This in turn would create less air pollution. Public

transportation is the solution to our air pollution problem. People

need to stop using their cars and find other ways to get places.

Public transportation is the use of buses, trains, subways,

ferries, and other vehicles meant to carry a group of passengers.

The benefit of using public transportation is that there is only one

vehicle releasing air pollutants, as opposed to many cars. Consider

if 50 people rode a bus instead of driving their cars. That would

eliminate a lot of gasoline and emissions!

Public transportation has other benefits, too. If this mode of

travel were put into effect everywhere in the United States, it could

greatly improve traffic problems on the streets. It would also save

people money that they would be spending at the gas pump. Having

fewer cars on the road also reduces the use of fossil fuels that are

slowly being used up. These fossil fuels are not renewable resources,

meaning we cannot create more fuel once it is all gone.

Some people have supported the use of electric or hybrid cars as

an alternative to gas-powered cars, but I disagree. These vehicles still

involve the use of gas in some cases. They are also expensive and are

still being perfected. Public transportation has already been proven to

work and improve the quality of our environment.

Public transportation may require a slight change in lifestyle,

but do not misjudge the amount of help it can do. Isn’t it worth it to

ride a train or bus when you consider that you are helping to keep the

air you breathe as clean as possible? We owe it to the planet to try to

protect and respect it. After all, Earth is the only home we have. Let’s

do our part to improve the world in which we live.
