According to one study, it’ll take about 1.2-trillion trees to absorb enough carbon to completely neutralize and reverse the carbon-emissions greenhouse effect that is (apparently) going on around the world. Deforestation in various places should be reversed; the land there isn’t good for much anyway except forest as they’ve been ranched to death. People plant green grass in their front lawns; how about shrubs, fruit trees, shade trees? Anyway, I thought it was interesting.
