How Important Tree For the Human


Indonesia in the last few years always bumped into disaster when seen disaster based on from environment problem and handlings wrong. wave flood pair, slide and drought has been annual disaster tradition never finished even per annum more has increased bad those disasters has been effect of global heating. Global heating that makes restless bations throughout world among others is caused by surplus karbondioksida (co2) on the air and that be impact from lost it a large part world forest tree - the tree absorbs karbondioksida, so that temperature increases and ice mount melts. We tree existence the important aware and forests to overcomes danger from global heating impact, and to anticipate forest preservation efforts the mentioned and tree plantings as much as possible and return forest mangrove must be action real from environment activity agenda be be explained in canopy.org (2006), every tree planted has contribution very big for environment and human life one big trees.

Benefit Forest

A forest is an area with a high density of tree. There are many definitions of a forest, based on various criteria.These plant communities cover approximately 9.4% of the Earth's surface (or 30% of total land area) and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Historically, "forest" meant an uncultivated area legally set aside for hunting by feudal nobility, and these hunting forests were not necessarily wooded much if at all (see Royal Forest). However, as hunting forests did often include considerable areas of woodland, the word forest eventually came to mean wooded land more generally.
