WHAT ARE FORESTS? Forests are vast expanses of lands covered with trees, plants and shrubs. They contain various water bodies like rivers, lake and streams Forests support a variety of wildlife like animals, birds, insects and aquatic life. Forests are the lung spaces of the world and absorb huge amounts of carbon dioxide and release oxygen The types of vegetation and animal life found in a forest depend on the region where it is located.
CROWN OF TREES The branchy part of a tree above the stem is known as the crown. Trees had crowns of different types and sizes. These had created different horizontal layers in the forest. These are known as understoreys Giant and tall trees constituted the top layer followed by shrubs and tall grasses, and herbs formed the lowest layer.

BENEFITS OF FORESTS Forest also acts as a natural absorber of rainwater and allows it to seep. It helps maintain the water table throughout the year. Forests not only help in controlling floods but also help maintain the flow of water in the streams so that we get a steady supply of water. On the other hand, if trees are not present, rain hits the ground directly and may flood the area around it Heavy rain may also damages the soil. Roots of trees normally bind the soil together, but in their absence the soil is washed away or eroded.
EFFECTS OF DEFORESTATION If forests disappear, the amount of carbon dioxide in air will increase, resulting in the increase of earth's temperature In the absence of trees and plants, the animals will not get food and shelter. In the absence of trees, the soil will not hold water, which will cause floods. Deforestation will endanger our life and environment.
