Burning fossil fuels, carbon emissions, it's both unnecessary, and damaging to the environment. Not just the environment, but Saudi Arabia owns ten percent of the USA due to their dependence on oil. The world could go renewable, could have gone renewable a decade or two ago, with no ill effects, if the right attitude was there, by the majority. It's brainwashing from the rich elite, those who have shares in oil, or whatever that causes the problem, but you know, these people are absolute bastards. Kill them I say.
