Deforestation
Nowadays, one of the biggest problems is deforestation, that destroys everything in its path, including several species of trees and wild animals that belong to forests and rainforests. Even though they still cover about thirty percent of the world’s land area, 15.3 billion are cut down every year and since humans started cutting down forests, 46 percent of trees have been felled, according to a 2015 study in the journal Nature. At this rate, these trees will have disappeared in a hundred years.

The reasons for indiscriminate logging are many, but most are related to urban growth and agriculture, for the reason that farmers need to cut down forests to make more space for their crops or for grazing livestock. In addition, commercial logging operations, which provide wood pulp and paper products to the world market, also participate in the logging of countless forests each year. Nevertheless, not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees.

Deforestation is an issue that must be solved due to the importance of trees in our lives. We need trees to absorb the carbon dioxide that we exhale and the heat-trapping greenhouse gases that we emit. If not, it will contribute to climate change.Also, it affects the animals, because eighty percent of them live in forests, so they could become homeless.

Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and retains heat at night. That disruption leads to more extreme temperature swings that can be harmful to plants and animals.
One example of this mass destruction of trees are the South American rainforests located in Brazil, such as Amazon rainforest:
