I don't personally buy it because there's always going to be someone claiming the collapse of civilization is nigh. During the shortages of food during COVID I saw channels I normally respected swerve a bit into prepperism or attempts to grow natural food in case of food chain collapse.
I do believe our climate situation is incredibly dire and we will need to use increasingly extreme measures to stop it. Executives need to start being punished properly for their extreme maleficence and disregard of public health, companies will need to face reckonings for hiding their crimes and everyone involved at the time charged. And we will also need to accept that infinite growth and the way we're growing isn't sustainable. But I think it's a problem that can be solved.
