Marxist ecology/Marxist geography are what I’m trying to go all the way to a PhD with but there are very few avenues for it. The work of theorists like Richard Lewontin, James O’Connor, David Harvey, Paul Burkett, Kohei Saito, and especially John Bellamy Foster is exactly the kind of stuff I want to do in applied science. Urban greenspace is one of those ultimate interdisciplinary subjects that demands being as radical as reality itself.
