Forest destruction i.e. deforestation has many after effects, it leads to soil erosion, loss of habitat, etiction of wildlife, floods & drought conditions.

Deforestation is the process of extensive cutting of trees, which finally leads to the destruction of forests as the trees are removed in large numbers, the water cycle gets disturbed which results in decrease in rainfall

Afforestation is the process of planting a large number of trees for increasing forest cover, while deforestation is the process of cutting trees in large numbers from the forest.

Deforestation means clearing or removal of forest by extensive cutting of trees, water cycle which goes on in the environment gets disturbed by lack of  sufficient number of trees. Trees increase the amount of rainfall due to transpiration, therefore if number of trees decrease rainfall also decreases, while other factors given in the options A, B & D increases.

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. A decrease in the species diversity progresses to extinction if left uncontrolled. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. As forests are the main habitat for the wild animals, their loss favors the extinction of the same.

When there are no more individuals of a species (plant or animal) alive anywhere in the world, the species is said to be extinct. Extinction is also known as the process of dying out. The process is a completely natural part of evolution. But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as large body size, habitat loss, small population and position at a higher trophic level favor extinction. Since the species residing in the tropics have their major habitat in the form of forests, thus deforestation causes, extinction of such species.

Since deforestation means cutting down of trees. So, it will result in desertification of an area, global warming because of increase in CO$ _2$ in the environment since plants are not available to fix it by photosynthesis, and can cause drought because of imbalance in water cycle of an area. But, deforestation will never cause forest fires because the forests are not available to catch the fire as they are being cut down in case of deforestation.
