They do this by collecting and filtering rainwater, that becomes my groundwater. I read that the porous soil created by decomposing leaves, bark, and tree trunks act as a huge sponge, absorbing water and purifying it as it seeps into the ground. Of course, the decomposed leaves, branches, and tree trunks, become a part of and further enrich the soil. Through their growth, transpiration, and death, trees transfer minerals and nutrients from air water and soil. And they stabilize the soil and keep it from eroding.
Trees also help prevent droughts by maintaining steady stream flows into drier seasons.
But, scientists say, the Global benefits of forests are even more important. Many species survive primarily in forests. In fact, one half forms of life on the planet, live in forests. A forests ecosystem serves as a critical medium for evolution. Without the forests, much of life on earth would be unable to adapt and evolve to new forms.
