If your goal is environmental health, using less land, less water, then you're better off tackling the larger cause: animal production. It dwarfs crops by those metrics.
I use Common Lisp, and now sometimes Clojure. I don't get why folks call Clojure a modern-Lisp. I miss the cons cell abstraction, the multiple values support, condition system, the fast start-up times, the native compilation, and executables.
Stacktrace in Clojure with no possibility to restart also make me sad.
