Some 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 these views and give your own opinion

For nearly a hundred years, the

world

has been facing extreme environmental

problems

. It is a harsh period for all

species

living on

earth

, numerous

plants

and

animals

are becoming extinct, and the ecology balance is under threat. Some believe that the main environmental problem the

world

facing now is the

loss

of biodiversity, but others argue that there are more crucial

problems

to the

earth

. From my perspective, I agree with the former. Over hundreds of millions of years, the

world

’s ecosystem has its own cycles. The cycles of living include every different

species

on the

earth

,

thus

all

plants

and

animals

, either living on land or in water, are important. With more

species

becoming extinct nowadays, the cycles have been damaged, the balance is no longer balanced. At the same time,

due to

the integrity of the

world

ecosystem, collective consequences among

plants

and

animals

have occurred.

For example

, the northwest part of China was once endless grassland where rabbits, wolves and sheep lived. But as the number of wolves decreased quickly, the number of rabbits and sheep rocketed. Since their food

, making it a desert where just a few

species

could live. In a word, the

loss

of one

species

could be extremely destructive to the

world

.

In contrast

, there are indeed more environmental

problems

that we cannot ignore. But the actual reasons for these

problems

, including global warming and the greenhouse effect, are closely related or even caused by the

loss

of biodiversity. So, the extinction of

animals

and

plants

is clearly more important than others.

To conclude

, the

world

is facing a great deal of

problems

, each is important to the whole ecosystem. But, the

loss

of biodiversity is the crucial problem of the

earth

which people have to grasp.
