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 ]
Logging is the process of cutting down trees for timber or other purposes. [18] [19] [20] It is a major industry in many parts of the world, and it is essential for providing wood for construction, furniture, and other products. There are two main types of logging: Clear-cutting: This is the practice of cutting down all of the trees in an area.
Planting trees in tropical climates with wet seasons has another advantage. In such a setting, trees grow more quickly (fixing more carbon) because they can grow year-round. Trees in tropical climates have, on average, larger, brighter, and more abundant leaves than non-tropical climates.
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 ...
Regarding the effects of afforestation on long-term carbon stocks and carbon sequestration these decrease when trees are less than 5 years old and increase quickly thereafter. [86] This means trees from monoculture planting that do not survive never reach full potential for carbon sequestration to offset China's carbon output.
The drive to banish pollution, caused mainly by sulphur dioxide (SO2) spewed from coal plants, has cut SO2 emissions by close to 90% and saved hundreds of thousands of lives, Chinese official data ...
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.
The Environment Ministry blamed the increase on weak law enforcement and a lack of supervision from local authorities, with land clearance as the primary cause of the fires. [ 17 ] Between 1990 and 2000 20% of the forest area in Indonesia had been lost (24 million ha) and by 2010, only 52% of the total land area was forested (94 million ha). [ 18 ]
