The environmental benefits of trees are broad. Trees are anti-pollutants, carbon-sinks, air conditioners and balancing weights to the ecosystem. These benefits can be grouped into four.
Atmospheric cleansing by absorbing carbon dioxide (CO2) and releasing oxygen through photosynthesis.
Storing carbon and keeping it out of the atmosphere. Half the weight of an adult tree is carbon.
Water cycling - , trees maintain rainfall when their roots absorb water from the soil and is released it into the atmosphere.
