Key questions scientists will need to address are how global reforestation might affect Earth’s surface albedo (reflectivity) and evapotranspiration. 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 Earth’s 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?

I really don't understand these our scientists. One day they are coming with the fact that deforestation is the reason why the air is not of good quality to breathe in and then they suggest that planting trees would solve the problem and the world began the planting of the trees even to the extent that we have a world planting tree day. Now, coming up with this means that they are saying we got it all wrong and we are even causing more damage with tree planting. It seems there is no way to please the ozone layer.

Even with so many efforts for tree planting, it is still not enough due to overpopulation high mortality rates. We cant catch up and we continue harming our environment. But thanks to these efforts of caring for our mother nature through this initiative, people become aware and being educated of the effects of abusing our environment.
