Why "change these human tendencies"? They're part of what's made us what we are today, and I don't think that undisputed mastery of an entire planet is such a bad place for a species to be. And even if you don't feel the same way, it's hard to see how undisputed mastery of only one planet gives humanity a better chance to eventually engineer itself into something more what you'd like it to be than does undisputed mastery of several.
