If you could magically eliminate all use of fossil fuel use billions of people would die in a few short months. No transportation of food and supplies to city dwellers, or efficient farming for that matter. Humankind with it’s current population relies upon fossil fuels use for it’s very existence. It’s easy to yammer about climate change but better to support the development of mitigating solutions. There’s big money in that, and I’m not taking about governments collecting taxes. Capitalists will bring solutions because that will make them rich.
