In the near term and locally, says Saatchi, forest restoration may actually have a warming effect. As the trees mature, the new forest canopy cover would presumably make Earths surface albedo darker, particularly in the Northern Hemisphere during periods of snow cover, causing it to absorb more heat. Increasing forest cover, particularly in the tropics, will increase evapotranspiration, causing a cooling effect. With Earth already warming significantly due to greenhouse gas emissions, will forest reforestation on a global scale have a net warming or cooling effect on our planet, and will the benefits of reforested areas absorbing more carbon outweigh their increased heat absorption?
Planting trees is very important for mother Earth and also to support all kind of race. It not only keeps check of O2 and CO2 in system but also keeps reduces harmful gases. Also, it provides habitats to many animals , bear fruits and also keeps earth colder. It also checks deforestation and kee checks on ground water.
