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.
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 ...
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 ]
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.

Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests , it is used by foresters to create certain types of forest ecosystems and to promote select species [ 1 ] that require an abundance of sunlight or grow in ...
Carbon emissions from deforestation is an important issue to look at with the increasing problem of global warming.Currently, about 4% of B.C.′s total green house gas (GHG) yearly emissions are from deforestation, which is quite a low percentage compared to B.C.'s total GHG emissions, and works out to be about 6,200 hectares of forest land is converted to non-forest use per year.
