It’s an especially bg problem in the rain forests. The Amazon is the most popular one. Many species of life live in these areas that cannot survive anywhere else in the world. So it’d be almost like someone coming in and mowing down Manhattan. Also, trees provide oxygen and naturally filter pollutants in the air that are harmful to us and other air breathing animals. They’re also quite possibly destroying plant and animal species that have not even been discovered yet. According to scientific estimation, 35- 150 species of life [plant, animal, fungi, etc.] become extinct every day. By destroying habitat, we destroy them.
