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.

Brazil's soy moratorium dramatically reduced Amazon deforestation
(01/23/2015) The moratorium on forest conversion established by Brazilian soy giants in 2006 dramatically reduce deforestation for soy expansion in the Amazon, and have been more effective in cutting forest destruction than the government's land use policy in the region, finds a study published today in the journal Science.
Company chops down rainforest to produce 'sustainable' chocolate
(01/20/2015) A cacao grower with roots in Southeast Asia’s palm oil industry has set up shop in the Peruvian Amazon. The CEO of United Cacao has told the international press that he wants to change the industry for the better, but a cadre of scientists and conservation groups charge that United Cacao has quietly cut down more than 2,000 hectares of rainforest.
High deforestation rates in Malaysian states hit by flooding
(01/19/2015) Five states hard hit by flooding last month in Malaysia had high rates of forest loss in recent years, bolstering assertions that environmental degradation may have worsened the disaster. According to satellite data from researchers led by the University of Maryland's Matt Hansen and displayed on Global Forest Watch, the states of Johor, Kelantan, Pahang, Perak, and Terengganu each lost more than 10 percent of their forest cover between 2001 and 2012. Loss was greatest in areas with dense tree cover.
