The Source of all the Fuss:  Oil

It likely causes more than pollution in our environment.  The sooner we end the drilling and production of this human killing toxin the better.  However we still need it and can not go without it until significant replacement energies are available and in use; therefore, we must continue drilling and producing. It's inevitable that as we humans advance that some of our energies may be found to be harmful to life, but if that energy is the primary source of energy we must reason that time is needed to research, produce and market the replacement before we abandon the latter.
