Answer:
Forest areas can reduce the expansion of the deserts because it does not allow the soil particles to get eroded from those places
Explanation:
Forest are the regions that are comprised of vast vegetation-covered areas. These forest regions are often cut down in order to set up urban areas, construct buildings and other commercial buildings. This directly affects the soil as it loses its fertility and in the regions where there occurs a lesser amount or no rainfall, the places are most likely to undergo the process of desertification.
The forest can prevent the spread of desert areas. It is because planting more trees will lead to increasing vegetation and decreases the cause of desertification. The process of erosion decreases and the speed of the prevailing wind also gets reduced due to the presence of vegetation. Afforestation must be done significantly in order to alter a dry land into a green vegetation covered area.
In the northern part of China, the forest areas are highly affected due to the deforestation process. The trees are cut down in order to make furniture, construction purpose, make medicines, and other purposes. The total area of the forest-covered regions in northern China has reduced significantly over the last few decades.
