Over the past 40 years, the greatest injustice has occurred in the world: twenty percent of the Amazon rainforest has been razed. People who cut down trees profit from stealing wood and land from people in the Amazon rainforest. Its indigenous tribes are being driven out by black market sellers and losing their homes. Mass extinctions of animal species have occurred and will continue to occur with industrialized corporations encroaching on the world's largest natural rainforest. With twenty percent already destroyed, oxygen in the atmosphere has decreased significantly. Each year, an area larger than the state of Maryland will be destroyed, along with the humans, ecological plants and animals that reside there. The Amazon rainforest is home to approximately 400 indigenous tribes and is the ancestral home of more than a million tribal people. These indigenous peoples became extinct due to injustice groups who cut down the trees and took over the lands that the indigenous tribes called home over the past centuries.

By cutting down rainforest trees, we are gradually causing the destruction of planet Earth and its natural resources. The animals and human tribes that live in the trees and rivers of the Amazon are also at risk of extinction. We are destroying ourselves by cutting down trees and if this does not stop, scientists believe that by the middle of the 21st century, rainforests could disappear completely; Earth will be an uninhabitable planet and it will all be our fault. This is without a doubt the greatest injustice ever committed by humanity..
