The whole world has been formed already by our presence and will continue to be. Humans modify our environment, for good and ill, and this is happening in all cultures and at all scales of civilization. Gardening proves microscopically what happens on the macro scale. To presuppose that is hubris is one way of looking at it, but a very narrow one.

The real fault in your reply, besides missing the substance of mine, is that framing such things as “hubris” doesn’t really help us weigh the value of the idea. At most it’s a critique of ambition, but an idea’s ambition isn’t related to its validity.

Also, wanting other humans to flourish is nearly the opposite of vanity.
