Question

The large-scale deforestation that is happening all over world is causing:
(A) Loss of biodiversity
(B) Soil erosion
(C) Global warming
(D) All of these

Answer 1

As we know that deforestation is the permanent removal or clearance of trees in order to make room for something other than forests. This process can include clearing the land for agriculture or grazing of animals, or maybe using timber woods for fuel as well as paper manufacturing and for many other things. But this large-scale deforestation has adverse effects on the environment.

Complete answer:
Let us discuss about deforestation and its adverse effects as follows:-
-Deforestation: It is the permanent clearing or the removal of a forest or stand of trees from land which is later converted into non-forest use. This can involve conversion of acres of forest land to ranches, farms or maybe urban use.
(A) Loss of biodiversity: Deforestation leads to the decline in biodiversity and on a global scale, it causes the extinction of many species as well due to loss of their habitat.
(B) Soil erosion: Soil erosion occurs when the soil is free and not tied up by the roots of plants and trees. When an area is deforested, the soil loosens up and can easily be eroded by heavy rains and storms.
(C) Global warming: Plants and trees evolve oxygen and intake of greenhouse gases like carbon-dioxide which is one among the greenhouse gases that leads to global warming. Due to deforestation the amount of carbon dioxide increases, which causes global warming.
-The most concentrated deforestation happens in the area of tropical rainforests. As we know that about 31% of land surface on Earth is covered by forests and around 16 -18 million hectares of forest are slashed every year.
-The effects of deforestation on ecosystem are as follows:-
-From the above data we may conclude that the correct option is (D) All of these.

Note:
The other serious effects of deforestation are as follows:-
-Many diseases spread around the environment due to loss of trees as we lack oxygen.
-Also pollutants increase in the air level which is very harmful.
-It also causes landslides which are due to soil erosion.
