If we destroy Earth, humanity is done.

Mars is bullshit. All of space is bullshit. We will never, ever, ever live there. It's a pipe dream for nerds. It is an insane waste of money and resources. There is no way to make it work. Oh rockets are better? Irrelevant. Radiation will kill you.

Carbon capture is a naked ploy by fossil fuel companies to sell more oil. It does not work. Geoengineering is insane and also does not work. Carbon credits are a scam.
