Deforestation

It’s the conversion of forested areas to non-forest land by cutting down trees done by humans or naturally caused by fires. Forests are important for quite a few reasons, for example, tropical forests compose only 7% of the earth's land surface, but are home to more than half of the species on earth. Another point is forests perform important ecological functions. It works as a Lung for this planet by taking out CO2 and increase oxygen production to prevent global warming.
