The Food and Agriculture Organization of the United Nations says that deforestation is the second-leading cause of climate change.

What is deforestation and its causes and effects?

Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate.

What are effects of deforestation?

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

What is the #1 threat to the rainforest?

Deforestation. One of the largest, and most well known problems in the Amazon is that of deforestation. While trees have been cut for logging, development and human expansion, it is actually farming that is causing the most extreme and drastic deforestation among much of the Amazon rainforest.
