Ancient Chinese texts make clear that some areas of the Yellow River valley had already destroyed many of their forests over 2000 years ago and had to plant trees as crops or import them from long distances. [300] In South China much of the land came to be privately owned and used for the commercial growing of timber. [301]
After eight years of the moratorium, a study conducted in 2015 found that although the soy production area had expanded by 1.3 million hectares, only about 1% of the new soy expansion had occurred at the expense of forests. In response to the moratorium, farmers opted to plant crops on already cleared land. [43]
Berkeley Bayisa, an Ethiopian farmer, offers one example of why deforestation occurs. He reported that his district was once forested and full of wildlife, but that overpopulation caused people to come and clear it to plant crops, cutting all trees to sell as firewood. [26] Ethiopia has lost 98% of its forested regions in the last 50 years. [25]
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. [ 39 ] Habitat loss is perhaps the greatest threat to organisms and biodiversity. [ 40 ]
Forests are an important part of the global carbon cycle because trees and plants absorb carbon dioxide through photosynthesis. Therefore, they play an important role in climate change mitigation .
The area destroyed in the first half of 2022 is 80% larger than the same period in 2018, the year before Bolsonaro took office, according to an analysis from the Amazon Environmental Research ...
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [42] [43] [44] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [45] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [46]
