Tarsand bitumen is possibly more of a polluter and contributor to global warming potentially than coal fired plants. Nuclear waste is a major problem left undetected by innocent people who are suffering its consequences and it does contribute to global warming.

Global warming is anthropogenic and there is a lot of evidence for this.

Conservation and constructive utilization of energy can still allow for the necessary and comfortable survivability but there are too many corporate energy CEO's and Wall Street oil speculators that would rather get rich quick and sell out the well-being and health of the planet.

This is basically where the climate denier propaganda is coming from.
