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.

Next big idea in forest conservation? Privatizing conservation management
(03/07/2014) Is it possible to equitably divide the planet’s resources between human and non-human societies? Can we ensure prosperity and rights both to people and to the ecosystems on which they rely? In the island archipelago of Indonesia, these questions become more pressing as the unique ecosystems of this global biodiversity hotspot continue to rapidly vanish in the wake of land conversion (mostly due to palm oil, poor forest management and corruption. For 22 years, Dr. Erik Meijaard has worked in Indonesia. Now, from his home office in the capitol city, Jakarta, he runs the terrestrial branch of an independent conservation consultancy, People and Nature Consulting International (PNCI).
Peatlands biosphere reserve facing severe encroachment in Sumatra
(03/06/2014) An important reserve that contains a block of fast-dwindling lowland swamp forest in Riau Province is facing an onslaught of encroachment for illegal oil palm plantations, worsening choking haze in the region, reports Mongabay-Indonesia.
Scientists blast Australian leader's proposed ban on parks
(03/05/2014) A group of prominent scientists have blasted Australian Prime Minister Tony Abbott’s pledge to oppose the creation of any new protected areas in Australia. The Alliance of Leading Environmental Researchers and Thinkers or ALERT, a coalition of conservation scientists, said Abbott is sending the wrong message to the world in promoting industrial logging over protection of the country's native forests.
