I recently watched a documentary called No Impact Man where a guy and his family were trying to have no environmental impact for a year while living in N.Y. city, and I thought it was pretty interesting. He was admittedly doing it it in part to promote the book he would write from it, but also just to see what it would it would be like living a very minimalist life style. They tried to have zero waste and zero emissions. They used bikes for transportation and walked up stairs rather than use elevators. They even cut the power to their apartment and didn't use toilet paper. Part of it like the toilet paper was over kill but over all it was pretty interesting and the one thing that really struck me about the whole thing was how many of our goals are very similar across different economic and political ideologies. Those people, their friends, and their future customers for the book were extreme liberals but a lot of what they were doing fits in with prepping and being more self sufficient. For example they tried the clay pot in water using evaporation to keep food cooler because they didn't have electricity (didn't work that great). They also experimented with gardening (urban gardening). And they only bought food from local farmers and even touched on the organic label thing, which isn't necessarily a prepping thing but on a personally level it is really nice knowing where your food comes from and what's in it. I've personally been on a self sufficiency kick for a awhile now. I don't plan on trying to ever be completely self sufficient but I do want to be much more self sufficient than I currently am, and I liked the way they approached some of this. I have very different goals and reasons for trying to be more self sufficient than they had but there was a lot of cross over. They wanted no impact and zero waste for the "environment" and I want to be more self sufficient in order to improve my quality of life, but the two aren't mutually exclusive. It was an interesting documentary and would be worth watching if anyone gets a chance to see it. I don't think you'll get much from it in terms of prepping info but it was thought provoking in regards to how much of this ties in together.
