Energy usage is a self-imposed problem. We know how to generate massive amounts of electricity with zero emissions: nuclear energy. Insane self-described environmentalists successfully lobbied to make nuclear reactors nearly impossible to build in most Western countries, much to the delight of the coal industry. But laws can be changed, and if we're choosing between changing a law, and an environmental disaster, we should obviously change the law.

I'm pro-lab-grown-meat though; if it's a tasty source of protein that reduces animal suffering and reduces the environmental impact of the meat industry, why not?
