    However harsh and hostile Earth can become due to climate change. Rest assured, Mars is harsher and more hostile.

    Whatever terraforming efforts we put into Mars to change that, would be easier, cheaper and more effective put into Earth.

    Other factors favor Earth over Mars which are entirely unaffected by climate change:

    • Earth’s gravity is ideal for us
    • We have all our scientists, workers, vehicles, machines, resources and infrastructure here, not there
    • Earth has a magnetic field which shields us from cancer-inducing cosmic radiation. Mars does not.
    • Marth has sharp dust particles flying around, which are a nightmare for surface machinery. Earth does not.
    • …

    There literally is no planet B. Also, tomorrow (15th Sept) is another FFF strike (on Earth).

        Fridays For Future is a movement started by Great Thunberg. It’s goal is to put pressure on politics to fulfill the Paris agreement.

        FFF is doing strikes every Friday, with major events once in a while. Before the Covid pandemic, participant numbers reached millions worldwide. The next big one is today, with events around the globe: https://fridaysforfuture.org/action-map/map/

        In practical terms, a FFF strike is a regular, orderly, peaceful, announced demonstration, free and safe for everyone to participate. If your country supports these citizens rights, of course.

            Very well! Sunny weather, much more people than expected, good speeches, funny posters, amazing bands, no serious incidents. Now all that’s missing is politics listening to the scientist.
