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 ]
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 ...
Radial annual growth is an integrative index of tree physiological response to environmental variation. Working with Norway spruce , which can be expected to behave in some respects similarly to white spruce, Misson et al. [ 1 ] showed that a reduction in stand density alters the classical climate–growth relationship.

Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year.
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.
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
