Effects of Deforestation

The United States Environmental Protection Agency defines deforestation as the "permanent removal of standing forests. Deforestation is the clearing, destroying, or otherwise removal of trees through deliberate, natural, or accidental means. It can occur in any area densely populated by trees and other plant life, but the majority of it is currently happening in the Amazon rainforest. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people. It was only after the onset of the modern era that it became an epidemic. One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. Not only does deforestation threaten species known to us, but also those unknown.

What Is Deforestation? Definition, Causes, Consequences, Solutions

Deforestation , clearance , clearcutting , or clearing is the removal of a forest or stand of trees from land that is then converted to non-forest use. The most concentrated deforestation occurs in tropical rainforests. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses regardless of whether it is human-induced. Net change, therefore, can be positive or negative, depending on whether gains exceed losses, or vice versa. For instance, FAO estimate that the global forest carbon stock has decreased 0. In North America, the forest carbon stock increased from However, carbon stock decreased from

People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Direct causes of deforestation are agricultural expansion, wood extraction e. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation. The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors.

Deforestation

The collapse of the Classic Maya state is investigated from an ecological perspective. Settlement and palynological data from the Maya center of Copan, Honduras, are presented which indicate that substantial clearing of the upland pine forest had occurred prior to and during the abandonment of that urban center. A comparative use- rate analysis suggests that the increased clearing of pine was primarily caused by demands for domestic fuel wood by an expanding urban population. This forest mismanagement is directly linked to accelerated erosion rates which are considered primary elements in the collapse of the Maya state.

Фонтейн молча стоял. Сьюзан заглянула в распечатку через плечо Джаббы. - Выходит, нас атакует всего лишь первый набросок червя Танкадо. - Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом. - Не верю, - возразила Сьюзан.  - Танкадо был известен стремлением к совершенству. Вы сами это знаете.

Тот, конечно, был мастером своего дела, но наемник остается наемником. Можно ли ему доверять. А не заберет ли он ключ.

Фонтейн давно всем доказал, что близко к сердцу принимает интересы сотрудников. Если, помогая ему, нужно закрыть на что-то глаза, то так тому и. Увы, Мидж платили за то, чтобы она задавала вопросы, и Бринкерхофф опасался, что именно с этой целью она отправится прямо в шифровалку. Пора готовить резюме, подумал Бринкерхофф, открывая дверь. - Чед! - рявкнул у него за спиной Фонтейн.

 - Человек умирал, и у него было одно желание. Мы просто исполнили его последнюю волю. Беккер смягчился.

Сьюзан осталась стоять. - Коммандер, если вы все еще горите желанием узнать алгоритм Танкадо, то можете заняться этим без. Я хочу уйти.
