Do I save up for railroad+lumbermill combo later in game, or do I viciously denude them? I confess I'm a bit of a fan of state property or free market when I get them, and I've never tried Environmentalism (the benefit seems somewhat small, all things considered)... I'm sure that you want to axe jungles posthaste, but I'm not sure about the trees. These days I cut them to bits to support wonder building or something. I'm a bit of a noob though, so advice would be appreciated, even if it's "well it depends!" which I'm sure it'll be.
