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.

Can improved oil palm productivity and Indonesia's forestry moratorium go hand in hand?
(05/27/2015) An op-ed from Mongabay-Indonesia chief editor Ridzki R. Sigit, who calls for renewed efforts to boost smallholder productivity on Indonesia's oil palm plantations in the wake of the renewal of the country's moratorium on new concessions in primary forests and on peat.
Palm oil activist murdered in Jakarta
(05/23/2015) An Indonesian activist who opposed unbridled oil palm expansion was stabbed to death by a group of men before dawn this morning outside a nightclub in South Jakarta. Whether the attack was related to his activism or the spontaneous result of a barroom brawl is not yet clear. But Indonesian media are reporting that one of the assailants shouted that he was a soldier as he brandished the knife that killed Jopi Peranginangin, the 39-year-old head of campaigns for Sawit Watch, which strives for social and ecological justice in the palm oil industry.
Timber 'mass graves' uncovered as Malaysian authorities pursue illegal loggers
(05/21/2015) A crackdown on illegal logging in Peninsular Malaysia's largest continuous forest complex has uncovered three timber 'mass graves' – burial sites where valuable logs have been stashed beneath tons of earth to hide evidence. The loggers apparently made haste in fleeing the hilly terrain where they left the timber. A joint operation by Malaysia's antigraft agency and Forestry Department found parts of logs sticking out of the ground and the red earth still unsettled, indications their quarry had hurriedly concealed the felled trees.
