Explanation:
The cutting down of trees is commonly known as deforestation. It has become a major issue as a huge number of trees have been cut down in the past years. The trees of tropical forests are mostly affected because of the abundance and variety of trees in this region. These trees include the softwoods and hardwoods. Examples of some softwood trees are spruce, rubber, pine, and fir, whereas, hardwoods include oak, maple, and hemlock. These trees are mostly used to make paper, wooden furniture, palm oil and also shampoos. In addition to this, the trees are also cut down for building houses, grazing of animals, agricultural purposes and used as fire to cook food in remote areas.
The cutting down of trees affects the trees and plant species, and also the fertility of the soil decreases. The organisms existing in this region are also affected due to their loss of habitat.
