So what may happen if the government takes action to curtail the use of fossil fuels and promote "green" energy sources? Has anyone researched the effect tens of thousands of wind turbine farms will have on the relative motion between the Earth and its atmosphere? Has anyone researched the effect that thousands of square miles of solar panels will have when they capture the sun's energy and prevent it from reaching the surface of the planet? Has anyone researched how colonies of anchored buoys will affect the overall wave motion of the oceans? Has anyone researched the effect of mass tapping of geothermal energy?
Take any one or any combination of these "green" energy sources to a point where they are providing all of civilization's energy needs and what will be the effect? Has anyone thought about this?
I think the answer to our planetary woes is fewer people. We're growing like cancer on the Earth's surface. If we don't control our population, Mother Nature will and she's ruthless.
