The world`s natural resources are saliently important, meanwhile, as the world`s population bulges higher and faster, it is arduous to hold on to these precious assets.While all resources have their own irreplaceable vital function, I posit that forests are the resource that we should be give/place utmost priority concerned about reserving.Trees have the capacity for balance ecosystem and natural environment.Salient in maintain steady temperature on earth.First,the forest can gives off oxygen and absorbs carbon dioxide so that the earth maintains a relatively constant temperature.but,in recent decades,with ceaseless notable diminish of the wooded areas and skyrocket rise up of carbon dioxide emissions,the homeostasis of earth`s air circulation has been drastically disordered ,then lead to the "Greenhouse Effect." Second, trees hold topsoil in place and soften the shock of water on the ground.This is furthest or most extreme essential in rain forests. The decomposition of rain forests is rapid and because of this, the layer of topsoil might only be five to ten centimeters deep.Finally,they transpire water into the air, creating clouds, and therefore, rain.Without trees, this cycle is interrupted, and rainfall is drastically reduced to minimal levels.
Decreasing the probability of natural disaster occurrence and allay it`s impact on mankind.Flood is one of lethal natural disaster for man.In some regions of the world,the flood are more prone to form.Besides the natural itself factors,many parts of the catalysts are human activities such as deforestation in watercourse district.Trees are important to the watershed or watercourse ecosystem because they defend streams from debris and silt. If the trees were all removed, there would be nothing holding back this dirt and soil from our rivers, destroying the aquatic environment. As a consequence, when the rain precipitated than usual, the silted watercourse cannot let the water run properly,then the water overflow the river-way and result in much damages.
Beautifying the environment and surroundings of human being living is one typical merit of the woods. One side,The wooded zone furnish natural beauty to a place either in countryside or in city.This is very crucial for tourism, as many visitors enjoy going long hikes through wooded areas, and taking in the beautiful scenery.In countryside, appropriate plant some trees are instrumental in growing of crops on arable lands.In city, the trees can also alleviate the pollution in city and make city a better place to living.For instance,trees acan absorb dusts and sands in air, in china Capital city-Beijing,sandstorm is severely percussion on citizens everyday life,part of reason is that the cover of trees in Beijing is extremely lower than other city of world.It is true that there are much more natural gems/jewels needs to be protected such as clean water,cherished animals.Nevertheless, the reserving of forest is a more imminent hazardous to tackle for human being and also is a prerequisite for the conservation of other pretty  valuable resources.
