That is the principal cause of global warming. The more trees there are, the more carbon dioxide is absorbed, and the less global warming we have. Because tree cover offsets global warming, it mitigates these effects. Serving as an Orchestrator of Ecosystems Driving the Hydrological Cycle Trees help drive the hydrological cycle, which carries water from sea to air to land and back to the sea again. Without this cycle vegetation would not exist.
Trees absorb vast amounts of water through their roots and leaves.
The operation of this cycle in forests, especially ones with larger and more mature trees, can in itself create and maintain micro-climates that generate added rainfall and support rich and diverse forms of life not present in unforested ecosystems. Who Planted Trees. Among them are the following. We consume vast quantities of fruit, nuts and other foods from trees. Energy Source Wood remains a fuel source for heat and cooking in much of the world.
