Exactly What Role Do Trees Play in the Environment?

Trees play an important role in our environment. They help to clean the air we breathe, filter the water we drink and provide homes for wildlife.
Trees also help to prevent soil erosion and provide shade, making them an essential part of a healthy ecosystem.
However, trees are being cut down at an alarming rate. Every year, millions of acres of forest are lost to deforestation. This not only destroys habitat for animals and plants but also contributes to climate change.
Trees help regulate the Earth’s temperature by absorbing carbon dioxide, a greenhouse gas that contributes to global warming. When trees are removed, the carbon they have stored is released into the atmosphere, furthering climate change.
In addition, deforestation leads to soil erosion, which can cause flooding and other problems. We must stop cutting down trees and start planting more. Trees are essential for life on Earth, and we cannot afford to lose them.
What Are the Most Prevalent Types of Trees on the Planet?
There are an estimated 60,065 species of trees on the planet, though this number is constantly changing as new species are discovered and others go extinct.
