Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
Deforestation in the United States was affected by many factors. One such factor was the effect, whether positive or negative, that the logging industry has on forests in the country. Logging in the United States is a hotly debated topic as groups who either support or oppose logging argue over its benefits and negative effects.
Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]
However, massive deforestation for economic development threatens its forests and ecosystems. As of 2015, the country has one of the highest rates of deforestation in the world. [47] Deforestation has directly resulted from poorly managed commercial logging, fuel wood collection, agricultural invasion, and infrastructure and urban development.
American environmentalists have campaigned against nuclear weapons and nuclear power in the 1960s and 1970s, acid rain in the 1980s, ozone depletion and deforestation in the 1990s, and most recently climate change and global warming.
In the 1980s and 1990s, the forests of Borneo were levelled at a rate unprecedented in human history, burned, logged and cleared, and commonly replaced with agriculture. The deforestation continued through the 2000s at a slower pace, alongside the expansion of palm oil plantations.
Deforestation in Brazil — which threatens the Amazon Rainforest, pictured above, — could hit an all-time low in the next 1-2 years, one government official said this week. (Reuters/Ueslei ...
Since 1990, it is estimated that some 420 million hectares of forest have been lost through conversion to other land uses, although the rate of deforestation has decreased over the past three decades. Between 2015 and 2020, the rate of deforestation was estimated at 10 million hectares per year, down from 16 million hectares per year in the 1990s.
