The remaining deforestation primarily results from small-scale subsistence agriculture [11] and mechanized cropland producing crops such as soy and palm. [ 12 ] Satellite data from 2018 revealed a decade-high rate of deforestation in the Amazon, [ 13 ] with approximately 7,900 km 2 (3,100 sq mi) destroyed between August 2017 and July 2018.
Some claim that rainforests are being destroyed at an ever-quickening pace. [48] The London-based Rainforest Foundation notes that "the UN figure is based on a definition of forest as being an area with as little as 10% actual tree cover, which would therefore include areas that are actually savanna-like ecosystems and badly damaged forests".

For the 300 years following the arrival of Europeans, land was cleared, mostly for agriculture, at a rate that matched that of population growth. [7] During the 19th century, while the U.S. population tripled, the total area of cropland increased by over four times, from seventy-six million to three hundred nineteen million acres.
When we think of the word "Amazon," we can easily free-associate to "rainforest." Of course, there's another free association that's far closer to home: Amazon.com . If Apple as envisioned by the ...
More than 50% of wetlands in the U.S. have been destroyed in just the last 200 years. [8] Between 60% and 70% of European wetlands have been completely destroyed. [13] In the United Kingdom, there has been an increase in demand for coastal housing and tourism which has caused a decline in marine habitats over the last 60 years.
In rare cases, a conservation reliant species may gain some measure of disease protection by being distributed in isolated habitats, and when controlled for overall habitat loss some studies have shown a positive relationship between species richness and fragmentation; this phenomenon has been called the habitat amount hypothesis, though the ...
This week, meet a “scuba-diving” lizard, marvel at a spacecraft’s longevity, explore hidden physics in a painting, unravel the origins of a “lost prince,” and more.
Deforestation in Central America is one of the environmental problems that is linked to the settlement of agrarian frontier areas by land-seeking farmers and commercial agrarians, who facilitated the conversion of forest land to pasture, more expansion of cash crop like coffee, banana, logging activities, pasture and fuelwoods among other urbanization activities.
