Deforestation takes place all around the world but is often most associated with tropical rainforests since that is where clearance of forest is happening at a great rate at the present time. Some of this clearance involves slash and burn farming techniques.

Some of this clearance involves slash and burn farming techniques. This is where the trees are chopped down and then burnt, leading to the release of large quantities of carbon dioxide and smoke into the atmosphere. The ash from the burnt trees and vegetation fertilizes the ground for a while but after a few years, the soil becomes too poor to support agriculture and so a new area is slashed and burnt. The biggest problems are when deforestation occurs on an industrial scale. Large areas of rainforest are lost each year to mining, and exotic timbers, like teak and mahogany, are deliberately and illegally felled for furniture making and building. Deforestation is also used to provide land to grow crops for making biofuels and to provide cattle and rice fields for food production. Although there are still a lot of trees around, the area covered by forests is a tiny fraction of what it was before humans started to clear the forests in order to grow their crops and build their settlements. Removal of trees contributes to global warming by removing the chance for carbon dioxide uptake by those trees, so less carbon dioxide is removed from the air. It reduces biodiversity and exposes the soils to erosion creating barren land, flooding, mudslides and landslides. Deforestation can nowadays only be prevented by political means in the countries involved, but the economic loss to those countries is a major issue. Show less
