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.

Green investors urge companies to clean up palm oil industry
(12/04/2013) A coalition of investors and asset managers is urging stakeholders in the palm oil industry to adopt policies that exclude deforestation and human rights violations from their supply chains. The call, coordinated by Green Century Capital Management, was issued in the form of letters sent to 40 major palm oil producers, financiers and buyers.
Brazil could boost agriculture without destroying forests
(12/03/2013) Brazil could substantially boost its agricultural output while increasing protection of its native ecosystems, finds a new analysis published by the Climate Policy Initiative (CPI), an international think tank.
Plantations used as cover for destruction of old-growth forests in Myanmar
(12/02/2013) As Wild Burma: Nature's Lost Kingdom airs on the BBC, the forests documented in the series are increasingly being cut down, according to a new report by U.S. NGO Forest Trends. The report alleges that wide swathes of forest are being cleared in ethnic minority areas of Myanmar (also known as Burma), ostensibly for palm oil and rubber plantations. However after the lucrative timber is extracted, the report finds little evidence that the companies involved are serious about establishing plantations.
