What is deforestation?

Britannica.com defines deforestation as the clearing or thinning of forests by humans; however, several other sources do not define deforestation as something that is solely happening because of humans. Deforestation is simply the loss of previously forested areas, and it could be caused by humans or natural factors such as fire or even climate change. More often than not, deforestation is happening because of human actions. In many areas, farmers cut forests down in order to make more room for crops or grazing livestock. Logging operations also have a huge impact on forests. Those logging operations are providing trees for the world's wood and paper products. Additionally, deforestation might be occurring in order to make room for expanding cities. It isn't only the trees that suffer from deforestation either. The forests themselves are habitats for millions of species of organisms, and those species struggle to survive without the forest. Finally, deforestation impacts climate change. The water cycle is thrown off, average ambient temperatures are changed, and even the re-absorption pace of greenhouse gases is changed in areas suffering from deforestation.
