Document Summary
Hurricane jeanne - caused national disaster in haiti (only 3% forest due to deforestation) while dominican republic (60% forest) was able to recover fairly quickly. Extreme poverty is one of the causes of deforestation (consumed by immediate needs) and powerful barrier to forest restoration and sustainable management (doomed cycle) Forest contain about 75% of world"s biodiversity. Wood and paper products ( billion to world economy every year) Most services not assigned monetary value, but loss of these services when forests disturbed/destroyed economic consequences. Forests play a key role in hydrologic cycle (roots absorb water, water evaporates from. Forests diminish the direct runoff of rainfall and reduce the risk of flooding, remove leaves) loss of forest often leads to decrease in rainfall sediments and dissolved chemicals from the runoff water. Forests store large amounts of carbon (photosynthesis remove carbon dioxide from atmosphere and store) deforestation reduces the total global forest carbon storage.
