Some argue that we should use cleaner energy sources to protect the environment, even though they are more expensive than traditional energy sources like coal and oil. To what extent do you agree or disagree?

While most countries around the

nowadays chose coal and oil as main sources of

energy

, some

people

claimed that we should use green

energy

in order to alleviate the environmental problems. The following paragraphs will explain why I strongly support the suggestion to draw upon cleaner

energy

Use synonyms

.

First

and foremost, as human beings, it is our responsibility to protect the natural

world

Use synonyms

by any possible means including give up some conventional ways of obtaining

energy

Use synonyms

. Since all sorts of current human activities take place on Earth, undoubtfully, the abuse of fossil fuel has become the culprit of series of environmental issues.

For example

, when fossil fuels are burnt in a car engine, a large amount of CO2, along with other greenhouse gases---especially these are not biodegradable---is eliminated into the atmosphere, which is responsible for some severe environmental issues

such

as air

and global warming. Noticing

such

harsh weather are proofed to have a long-lasting impact.

Therefore

Linking Words

, in order to build a cleaner

world

Use synonyms

, we must replace

such

Linking Words

harmful fuels.

On the other hand

, consider the monetary matters, the opponent of the above statement says that

instead

Linking Words

of exploiting an alternative source of

energy

Use synonyms

, it is better to spend money elsewhere

such

as growing trees, or develop sewage treatment which is proofed to be helpful in terms of cleaning.

Nevertheless

Linking Words

, the problem won’t be solved yet, unless we remove the sources of

pollution

Use synonyms

.

Consequently

Linking Words

,

people

Use synonyms

still have to spend extra fortunes on handling

such

Linking Words

contamination. What’s more,

such

Linking Words

things are out of concern if we simply use cleaner

energy

Use synonyms

, namely, they produce no pollutants in the aftermath. In a word, rather than find ways to deal with the pollutants after burning fossil fuels,

people

Use synonyms

should pay more attention to thoroughly eliminate the source of

pollution

Use synonyms

. To conclude, I take a side on the suggestion that

people

Use synonyms

should try alternative sources of

energy

Use synonyms

not merely because of the importance of the natural

world

Use synonyms

to humans but

also

a long-term approach to eliminate

pollution
