Earth surface are composed of 70% of water and 30% of lands or soil.
Therefore, whatever happens to our earth surface results to global warming.
Trees, waters and other natures protect our mother earth from direct heat of ultraviolet rays of sunlight, when these are gone, it will result to too much heat and even damage to our environment.
