Influence of human beings on the world's ecosystem is leading to the extinction of species and loss of bio-diversity. What are the primary causes of loss of bio-diversity? What solutions can you suggest?

In today’s world, human activity has a devastating influence on the environment and

this

, in turn, leads to the extinction of species of flora and fauna.

Firstly

,

this

essay will discuss the possible reasons for

such

a tendency and,

secondly

, it will analyse what can be done to solve

this

issue. On the one hand, the main cause of

loss

of bio-diversity is global warming which is being stimulated by people’s activities.

This

is because not only do factories produce a large amount of carbon dioxide

emissions

but,

moreover

, there is a high

level

of deforestation and

loss

of green zones.

As a result

, these carbon dioxide

emissions

trap the heat of the sun reflected from the Earth in the atmosphere and there are no trees that can clean the air.

Therefore

, these conditions might provoke global heating and a large number of creatures will lose their houses and some types of plants will die due to unexpected climate changes.

For instance

, one recent research has shown that the average temperature

level

has increased by 2% in the

last

two decades.

However

, there are possible solutions to

this

question, namely, government intervention and legislation.

This

is since not only can the authority introduce

pollution

permits to discourage companies to pollute but

also

they can create new laws that will put a maximum

level

of

emissions

per factory.

Hence

, since

pollution

permits will have high prices it will increase companies’ costs and they will try to find alternative ways how they can reduce the

level

of

pollution

.

Consequently

, the

level

of air

pollution

will be decreased

this

, in turn, will slow down global heating, and animals and plants will have some time to adjust to changes gradually.

For example

, one study has illustrated that when the government has introduced

pollution

permits in Ukraine the

level

of

emissions

has decreased by 10%. To conclude, the main reason why some animal species became extinct and there is a

loss

of bio-diversity is that human activity, namely

pollution

, and deforestation, stimulate an increase in temperatures.

This

, in turn,

to a

loss

of habitation of some creatures and plant extinction. Despite

this

fact, if the government intervene and introduce legislation

this

issue can be overcome since it will discourage firms from

pollution
