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.

Jokowi must strengthen Indonesia's forest moratorium, not just extend it: activists
(04/25/2015) Less than a month before the expiry of a moratorium on new licenses for land-based exploitation in primary forests and on peat, environmentalists are calling for the Indonesian president to not only prolong the policy but strengthen it too, hampered as they say it has been by chaotic implementation, weak enforcement, standards that don’t go far enough and, some suggest, a lack of political will to see it through.
Conservation in Myanmar: a cause for optimism?
(04/24/2015) Fifty years of relative political and economic isolation have yielded slow economic growth and contributed to the conservation of many of Myanmar’s native species. However, the dissolution of Myanmar’s military junta in 2011 marked the beginning of a new age of increasing political and economic liberalization and international engagement. Many experts fear that possible rapid development fueled by international investment, improved infrastructure and expanded transport networks, pose a grave risk to Myanmar’s biodiversity and forests.
Officials: Sumatran rhino is extinct in the wild in Sabah
(04/23/2015) There are no Sumatran rhinos left in the wild in the Malaysian state of Sabah, confirmed Masidi Manjun, the Tourism, Culture and Environment Minister, over the weekend. In 2008, conservationists estimated there were around 50 rhinos in the state. Five years later, it dropped that estimate to just ten. Now, it's admitted the awful truth: the wild rhino is very likely gone.
