I ask because I never see this mentioned anywhere, it's always about cars and coal and even cows, which seems silly to me. So, my question is about trees, if Global Warming is caused by CO2 isn't this directly related to the fact that we as people have spent the vast majority of the last 100 years chopping down every single tree in our path, every subdivision I see built today there are no trees, every week a new shopping center goes up where a wooded lot used to sit even though there are half a dozen empty ones around town. Without those trees the CO2 levels rise and in turn we get the symptoms of Global Warming. So in theory could we not slow down this phenomenon by keeping large swaths of land covered in trees, slowing down deforestation and working on ways to get and grow trees in urban settings? Or am I way off base and talking out of my backside with my limited high school knowledge? Of course I'm not so deluded as to believe we have enough land to plant enough trees.
