Trees help prevent floods

Some rainwater stays on the leaves, and it may evaporate directly to the air (the more water used in the watershed, the less remains to run off).Leaves reduce raindrop impact, and gentler rain causes less erosion.Tree roots absorb water from the soil, making the soil drier and able to store more rainwater.Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream. The above image is of a Yangtze logging site in China where a decade ago heavy rain brought huge flood to the Yangtze area, one of the main reasons why the flooding was so devastation was due to the mass deforestation of the area.
