Forests important for us because Forests play a key role in keeping our planet healthy. The treetops of the canopy layer of a forest lessen the impact of rain on the soil, and by doing so, reduce soil erosion.
The layer of leaves on the ground around a tree prevents the water from running off. The roots of trees hold the soil in place, and dead plants on the forests floor decompose to form humus, or organic matter that make the soil rich in the nutrients a plant needs.
Forests serve as a home to millions of animals, birds, and insects.
Most importantly, the trees in a forest absorb carbon dioxide and release vast quantities of oxygen to purify the air, while the water vapour released by leaves affects the humidity and rainfall in a Place.
