bearing in mind that only a small percentage of earths population have access to electricity, if we enabled all under developed countries in the world with fossil fuel electricity and heating systems, we would likely have to cover every sq inch of farmland in trees to combat climate change.rather than outright fighting the building of wind turbines (that in future times can be repaired at a fraction of the impact and pollution of replacing them) we should be putting pressure on the manufacturers of these systems and technologies to invest more in finding green solutions to using the polluting chemicals in the construction of turbines.
