Because a forest is meant to sustain life. When we destroy vast amount of trees especially in tropical forests, this is hurting the environment. Forests still cover around 30 percent of the world. It’s bad because it destroys a lot of the habitats and kills wildlife and disrupts nature! Instead of having to destroy forests for homes we have more area outside of rain forests where we won’t disrupt nature.
Hope this helped
Have a great day,
