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.

Gold mining expanding rapidly along Guiana Shield, threatening forests, water, wildlife
(10/22/2014) Gold mining is on the rise in the Guiana Shield, a geographic region of South America that holds one of the world’s largest undisturbed tract of rainforest. A new mapping technology using a radar and optical imaging combination has detected a significant increase in mining since 2000, threatening the region's forests and water quality.
Colombia reports drop in deforestation
(10/21/2014) Colombia has for the first time released an annual report on deforestation, revealing that forest loss during 2013 was lower than the recent average. The government says some 120,933 hectares of natural forest were cleared between January and December 2013.
'No forests, no cash': palm oil giants commit to sustainability, but will they follow through?
(10/21/2014) Four of Indonesia’s largest palm oil producers signed a landmark commitment in New York in September to further implement sustainable practices across one of the country’s largest commercial sectors. Then-President Susilo Bambang Yudhoyono and the Indonesia Chamber of Commerce (KADIN) witnessed the undertaking, which is hoped to expand the country’s palm oil industry while making it more environmentally friendly.
