ome people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say that there are more important environmental problems. Discuss both sides and give your own opinion.

Certain

species

in the world have become extinct and many are on the verge of extinction.

However

,

although

I agree that

this

is an important environmental

problem

, I do not believe that it is the most critical.

On the other hand

, the disappearance of any living

species

affects the environment. It is undeniable that every

species

on earth is a part of a delicate balance of the ecosystem. To illustrate, if a certain type of snake disappears, the number of mice that are the main food of snakes will increase.

As a result

, without the predator to control the number of mice, too many of them can lead to the destroying of corps and

also

an increase in the number of diseases which has mice as carriers.

However

, despite the obvious

problem

of extinction of a particular type of plants or animals, I still believe that

water

pollution

is more urgent. While it takes time for

species

to become extinct,

water

pollution

happens every day and its results can be seen quite rapidly. Many countries are encountering river and ocean

pollution

problems which are caused mostly at the hand of humans. Especially in countries with poor rubbish management, waste and garbage are dumped into a river and end up in the ocean.

As a result

,

water

becomes polluted and neither suitable for drinking nor marine animals to live in. These can lead to a serious food shortage in the future.

Finally

, the most worrisome environmental

problem

is global warming. Toxic fumes from industries, vehicles and farming contribute to releasing greenhouse gasses into the atmosphere and causing the temperature to rise in certain parts of the world.

Consequently

, many countries experience abnormal natural disasters

such

as flash floods and wildfires more than at any point in the history of mankind. These effects from global warming harm humanity directly whereas extinction of certain

species

has

indirect effects.

Thus

, it is sensible to prioritise and focus on solving the global warming

problem

first

. In short, While I agree that the loss of certain

species

of plants and animals is an important environmental issue, I still believe that

water

pollution

and global warming are far more critical and urgent.
