Jessica, I've just started a truly inspiring book. Rebecca Solnit's Paradise Built in Hill: The Extraordinary Communities That Arise in Disaster. (https://www.goodreads.com/book/show/6444492-a-paradise-built-in-hell)
All about the impulse to mutual aid and community self-sufficiency that's revealed after the shock and physical impact of natural disaster. With a side of government action that often makes things worse.
