Why are trees important to the ecosystem?
Trees absorb carbon dioxide and other dangerous gases and, in turn, replenish the atmosphere with oxygen. … Over 50 years, a tree generates $31,250 worth of oxygen, provides $62,000 worth of air pollution control, recycles $37,500 worth of water, and controls $31,250 worth of soil erosion.
How are trees sustainable?
At a basic level, trees remove carbon dioxide—a major greenhouse gas contributing to climate change—from the air during photosynthesis. Urban trees reduce energy use for heating and cooling homes in the U.S. by more than 7 percent.
How do trees reduce pollution?
Aside from cleaning the air for us, trees supply us with fresh oxygen to breathe. … Through the process of photosynthesis, trees are able to absorb carbon dioxide from our atmosphere and reduce the ‘greenhouse effect’, creating a less polluted, more sustainable world for our future generations.
