Deforestation is when humans remove a large amount of trees from forest to use as paper and many other commercial products. Deforestation effects many ecosystems and destroys them so they cannot be used by any animals again.
Forests cover about 30% of the world's land area and is home to 70% of the worlds land animals. Tropical Rain Forests alone holds 50% of the Earths wildlife and other organisms. 90% of Earth's primates live in the Rain Forest because the canopies of the trees have perfect protection and shelter for them. If the canopies are being destroyed so fast, the primates will not be able to adapt and eventually, they will die out.

Deforestation also causes climate change. Forests soil's are wet, but when the canopies are cut down, the soil loses its protection from the sun and it quickly dries out. This problem causes the water cycle to screw up because it has less water to evaporate and reuse. This can cause many deforest lands to become dry, lifeless desserts.
