It's easy to summarize, difficult to imagine, even more difficult to implement. Some of your steps even require fossil fuels, that's how deep we are in it. The resulting demand for alternatives for heat or fuel will make current deforestation seem like nothing. Any sort of agriculture big or small without some fossil fuel and/or fertilizer? Good luck with that in a good growing season.

I don't have a solution, as what we find ourselves in is a predicament that has none. It's just a matter of how things break, if we choose to be part of that fracturing, or just let it play out as we continue to cling to a teetering structure. Same problem, neither choice is better than the other. I'm guessing as a species we'll do what we always do and take the least amount of change for as long as we can, then we'll react, probably badly.
