Explanation: 

Detailed explanation-1: -Timber harvesting also interrupts the normal nutrient cycle of the forest, promotes nitrification and increases nutrient leaching thereby leaving the topsoil impoverished and susceptible to erosion.

Detailed explanation-2: -Increased Greenhouse Gases In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Healthy forests absorb carbon dioxide from the atmosphere, acting as valuable carbon sinks. Deforested areas lose that ability and release more carbon.

Detailed explanation-3: -Agriculture is the second main cause of forest conversion in the Amazon. In addition to deforestation, agricultural practices tend to cause significant soil erosion and river siltation, as well as aquatic contamination with agrochemicals.

Detailed explanation-4: -Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife.
