CONSEQUENCES OF DEFORESTATION
By Rhett Butler
| Last updated July 22, 2012
Rainforests around the world still continue to fall. Does it really make a difference? Why should anyone care if some plants, animals, mushrooms, and microorganisms perish? Rainforests are often hot and humid, difficult to reach, insect-ridden, and have elusive wildlife.
Actually the concern should not be about losing a few plants and animals; mankind stands to lose much more. By destroying the tropical forests, we risk our own quality of life, gamble with the stability of climate and local weather, threaten the existence of other species, and undermine the valuable services provided by biological diversity.
While in most areas environmental degradation has yet to reach a crisis level where entire systems are collapsing, it is important to examine some of the effects of existing environmental impoverishment and to forecast some of the potential repercussions of forest loss. Continuing loss of natural systems could make human activities increasingly vulnerable to ecological surprises in the future.
The most immediate impact of deforestation occurs at the local level with the loss of ecological services provided by tropical rainforests and related ecosystems. Such habitats afford humans valuable services such as erosion prevention, flood control, water filtration, fisheries protection, and pollination—functions that are particularly important to the world's poorest people, who rely on natural resources for their everyday survival. Forest loss also reduces the availability of renewable resources like timber, medicinal plants, nuts and fruit, and game.
Over the longer term, deforestation of tropical rainforests can have a broader impact, affecting global climate and biodiversity. These changes are more challenging to observe and forecast from local effects, since they take place over a longer time scale and can be difficult to measure.

Conservationists propose Dracula Reserve in Ecuador
(10/24/2014) Deep in the dark, cool forests of Ecuador and Colombia live strange and mysterious organisms. Some inhabit the trees and others stay to the ground, and many are threatened by human encroachment. Because of this threat, Rainforest Trust has launched a Halloween fundraising drive to help pay for the creation of the Dracula Reserve--named for its dramatic inhabitant, the Dracula orchid.
Google's new Gombe Street View lets users 'walk' along chimp trails and into Jane Goodall's house
(10/24/2014) Google Maps is now available for Tanzanian forest paths. Users can walk virtually along the same trails Jane Goodall has used for her decades of chimpanzee monitoring -- and even into her house.
Beef, palm oil, soy, and wood products from 8 countries responsible for 1/3 of forest destruction
(10/23/2014) Four commodities produced in just eight countries are responsible for a third of the world's forest loss, according to a new report. Those familiar with the long-standing effort to stop deforestation won't be surprised by the commodities named: beef, palm oil, soy, and wood products (including timber and paper). Nor will they be very surprised by most of the countries: Brazil, Indonesia, and Malaysia.
