Jungle burned for agriculture in southern Mexico.

Deforestation is the logging or burning of trees in forested areas. There are several reasons for doing so: trees or derived charcoal can be sold as a commodity and are used by humans while cleared land is used as pasture, plantations of commodities and human settlement. The removal of trees without sufficient reforestation, has resulted in damage to habitat, biodiversity loss and aridity. Also deforested regions often degrade into wasteland.

Disregard or unawareness of intrinsic value, and lack of ascribed value, lax forest management and environmental law allow deforestation to occur on such a large scale. In many countries, deforestation is an ongoing issue which is causing extinction, changes to climatic conditions, desertification and displacement of indigenous people.

In simple terms, deforestation occurs because forested land is not economically viable. Increasing the amount of farmland, woods are used by native populations of over 200 million people worldwide.

The presumed value of forests as a genetic resources has never been confirmed by any economic studies . As a result owners of forested land lose money by not clearing the forest and this affects the welfare of the whole society . From the perspective of the developing world, the benefits of forest as carbon sinks or biodiversity reserves go primarily to richer developed nations and there is insufficient compensation for these services. As a result some countries simply have too much forest. Developing countries feel that some countries in the developed world, such as the United States of America, cut down their forests centuries ago and benefited greatly from this deforestation and that it is hypocritical to deny developing countries the same opportunities: that the poor shouldn’t have to bear the cost of preservation when the rich created the problem .
