Easiest and most effective way to stop/reduce climate change

Why is it that we humans tend to think that complex machinery is always the best way to solve problems? why do we think that creating a machine to remove carbon dioxide from our atmosphere is the best way so solve climate change? That is because machines do the dirty work for us all the time, ex. a tractor makes it easier to mass produce grain and other farm produce instead of a farmer plowing the field with his oxen. I think everyone is on a straight mind set. Why don't people look at how we have avoided this crisis in the past, if machines were not invented back then, then what prevented or even stopped climate change 1 million, 10 million, or even 100 million years ago back when dinosaurs still ruled the earth and flowering plants continued to evolve? Nature. Chlorophyll (algae, plants, trees) absorbed carbon dioxide and produced oxygen, and by doing that, cooling the planet. To prevent climate change I propose planting trees. Its as simple as that, and to all the lazy people out there, yes we will now have to "do the dirty work". But the good news is that we, or the generation after us, or the generation after that, will not have to die because of horrendous storms (tornadoes, earthquakes, tsunamis, hurricanes five times bigger than Katrina), more good news is that we will have millions of beautiful trees to look at. We can't just stop cutting down trees, we have to plant trees! Save the enviroment, plant trees!
