Without a serious effort to eliminate heavy pollution by coal fired plants (acid rain, millions of tons of mercury, arsenic sent into the air and causing birth defects, autism, etc), gas fracking, biofuel cars, ships, planes, trains, etc - we will not be successful in increasing the quality of human life. That's why solar and wind power are so important, they can cut dramatically on air, water and soil pollution.
Even if you don't believe in climate change, here is a major reason to switch to solar, wind, renewables and electric transportation ► removing most chemical pollution from air, water, soil - therefore preventing the premature death of billions of people.
