Yes, I'm completely and utterly sick of people saying, "We can do both." We can't. We aren't. It isn't happening. You're believing in a fantasy for which there is no evidence at all.

I've been hearing your claim for literally 40 years and during that time we have only made negative progress on preventing the biosphere from destruction.

We aren't even trying to save our ecosystem. Let's see some progress on not destroying our ecosystem before we start to expend effort on a project like Mars that will take quadrillions of dollars and a century just to get started.
