Deforestation at large scale can be observed at:

The Amazon rainforest is the biggest tropical forest on the planet, and it is also the site where the most widespread deforestation on a large scale is happening. The cause of the loss of trees in the Amazon rainforest is mainly due to cattle ranching, which causes four out of five instances of deforestation, and also due to large-scale soybean farming and infrastructure projects like the Trans-Amazonian Highway. Even today, one out of five trees in this region is lost due to deforestation. Due to its large area, the extent of land cleared in this region every year is greater than that cleared in any other single forest area in the world.
