Deforestation
Deforestation is one of the biggest issues by which the environment is affected. It involves cutting trees for furniture, or that people need to cut lots of trees and that makes lots of animals loose their habitats and can also make some animals get extinct.
Also deforestation makes lots of forests become wastelands and increases desertification. Most people don’t know this but when you cut a tree it produces CO2 which affects the climate and destroys the ozone layer, imagine how much is produced when you cut a whole forest.
A thing we use every day is got from trees , paper but it takes lots of trees and forests to make paper .People who do it cut lots of trees to make all the paper we use.For furniture people have to cut lots of trees too, and they have two ways to cut , clear cutting which cuts all the trees in a zone which is safer for the people who cut and cheaper too.Selective cutting is the other way to cut but that is not so safe and is more expensive , but the way that affects less the environment is selective cutting because clear cutting throws all the bad wood away when they have already cut it and just waste it.
