Agreed, before we built cities we were cutting down forests for farmland. Before we built farms, we burnt down forests to create savannah to expand the grazing land so we could herd more cattle (yes, there was a disturbing trend 100,000's of years ago - up to about 1 million years ago - that wherever mankind lived, fire occurrence went through the roof) People conveniently overlook our past whilst condemning our present. I'm sorry to all those people who blindly don't see, but we are god. We aren't playing as this secular god, we have been it since long before we even acquired fire. At our present point we can change the world in a heartbeat. If an ice age begins, we have the ability to produce vast quantities of green house gasses far more potent than CO2 or methane. Similarly, if the planet starts heating dramatically, we have the ability to release vast quantities of SO2 into the upper atmosphere and force the planet into a global dimming cycle like it was in between the 1960's-90's. Similarly, with our construction of vast arrays of wind turbines there has been a noticeable decline in wind speeds in those areas. Incidentally, something many people have failed to remember from basic high school physics is that generators can act as motors and vice versa. If it ever came to it, we have the ability to change the direction of winds in localised areas. There's even debate over whether we have the ability to cause the formation of rain (we invariably can heat+water, it just takes a lot more effort than the cloud seeding hocus pocus method), and scientists around the world regularly cause lightening. Really, what do humans do that is not attributed to a god?
