Deforestation eliminates a great number of species of plants and animals which also often results in exposure of people to zoonotic diseases. [12] [237] [238] Forest-associated diseases include malaria, Chagas disease (also known as American trypanosomiasis), African trypanosomiasis (sleeping sickness), leishmaniasis, Lyme disease, HIV and ...
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest. It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
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.
Deforestation in Brazil's Amazon rainforest has skyrocketed to a 12-year high in 2020. Government data released on Monday (November 30) showed more than 11,000 square kilometers have been wiped ...
[10] [11] The relationship between deforestation and climate change is one of a positive (amplifying) climate feedback. [12] The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth.
As a result, the net loss of forest area is less than the rate of deforestation; and it, too, is decreasing: from 7.8 million hectares (19 million acres) per year in the 1990s to 4.7 million hectares (12 million acres) per year during 2010–2020. [36]
The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km 2) around 1920. [8] The forest resources of the United States remained relatively constant through the 20th century. [9]
According to the figures from the FAO (1997), only 22.8% of West Africa's moist forests remain, much of them degraded. [12] Nigeria has lost 81% of its old-growth forests in just 15 years (1990–2005). [13] Mass deforestation threatens food security in some African countries. [14]
