Phasing out fossil fuels is difficult, but that is only half the answer.  We must also stop eliminating OXYGEN PRODUCERS.  Plant a tree or two.  Pay attention to clear-cutting in this country and rain-forest depletion all over the world, fueled by greed for more and more 'things'.  Pay attention to the acres being converted from agriculture to housing.  Notice all the concrete and asphalt around closed factories and big-box stores.  We have houses and malls sitting empty and developers clamoring to build more, anywhere they find bare land.
