Trees absorb the pollutants present in the air and acts as a filtration device so that human beings can breathe clean air. The roots of the trees hold the soil together which prevents soil erosion. 100 mature trees can intercept 1,00,000 gallons of rainfall per year. A fully grown tree produces approximately 322 grams of oxygen per day. Besides these, trees play an important role of lowering the temperature and humidity as they can influence wind speed and absorbing the solar energy and radiating it back, thereby making our planet habitable and pleasant.
