I’m remember the Netflix documentary Wild Wild Country in which what effectively was a cult purchased a large plot of land that had been killed by something along the lines of overuse/neglect/etc. and all sorts of people scientists/lawyers/engineers came together and basically resorted it, made it arable and wild life returned. Shame it probably couldn’t happen without the cult aspect.
