Introduction and definition

 Before talking on a serious tone about opinions about the subject, it´s important to determine what is deforestation:

"Deforestation is the clearing or thinning of forests by humans. Deforestation represents one of the largest issues in global land use".
All the trees are removed from the land for many reasons to human use (construction is the most common use), which completely destroys the forest. Some times, even accidental fires or cutting a small amount of trees changes the way the forest is structured.
