Cutting down and clearing trees is second only to burning fossil fuels as a creator of carbon emissions. Fighting the climate crisis becomes inexplicably harder without forests
However, the United Nations Environment Programme report on "Making Peace with Nature" released in 2021 found that most of these efforts had failed to meet their internationally agreed upon goals. [58] Tropical deforestation: In most cases of tropical deforestation, three to four underlying causes are driving two to three proximate causes. [19]
Several studies since the early 1990s [30] have shown that large-scale deforestation north of 50°N leads to overall net global cooling [31] while tropical deforestation produces substantial warming. Carbon-centric metrics are inadequate because biophysical mechanisms other than CO 2 impacts are important, especially the much higher albedo of ...
2 March 2023: a study published in Science said that boreal fires, typically accounting for 10% of global fire CO 2 emissions, contributed 23% in 2021, by far the highest fraction since 2000. [59] 2021 was an abnormal year because North American and Eurasian boreal forests synchronously experienced their greatest water deficit. [59]
Other reasons include low education and inactivity from the government, [23] although the current government has taken some steps to tackle deforestation. [24] Organizations such as Farm Africa are working with the federal and local governments to create a system of forest management. [ 25 ]
Between 2001 and 2018, 27% of deforestation was from permanent clearing to enable agricultural expansion for crops and livestock. Another 24% has been lost to temporary clearing under the shifting cultivation agricultural systems. 26% was due to logging for wood and derived products, and wildfires have accounted for the remaining 23%.

Monarch butterflies, known for migrating thousands of miles (km) across North America, have experienced a decades-long U.S. population decline due to habitat loss caused by human activities such ...
Deforestation in the city of Rio de Janeiro in Brazil's Rio de Janeiro state, 2009. Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use.
