Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates. A study of the girth of 70,000 trees across Africa has shown that tropical forests fix more carbon dioxide pollution than previously realized.
Trees are cut down for use as building material, timber or sold as fuel (sometimes in the form of charcoal or timber), while cleared land is used as pasture for livestock and agricultural crops. The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue . [ 89 ]
Clear-cutting: This is the practice of cutting down all of the trees in an area. Clear-cutting is often used to create large areas of land for agriculture or development. Selective cutting: This is the practice of cutting down only certain trees, such as those that are mature or diseased. Selective cutting is often used to manage forests and ...
The trees that are no longer there can’t continue to convert carbon dioxide into oxygen, and the forests that grow back won’t capture enough carbon to break even for decades or centuries, if ...

Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. [9] Logging usually refers to above-ground forestry logging.
These effects are still felt today, particularly in areas where recovery has been slow or hindered by ongoing deforestation pressures. The war left a legacy of environmental degradation that affected not only the forests but also the communities that relied on them for resources such as food, timber, and fuel. [ 82 ]
Tree felling: The selected trees are cut down using chainsaws, harvesters, or other mechanized equipment. The felled trees are then prepared for further processing. Timber extraction: Once the trees are felled, loggers extract the timber from the forest by removing branches and cutting the tree trunks into logs of appropriate sizes for transport.
