The problem I have with folk who want to believe the world is doomed, Mike, is that in a way, they / you are cooperating / conforming to the system that wants us dead.
You / we, who have removed our original full support and cooperation from the old system that we know is/was destroying the planet for profit, are no longer useful to it, so it wants us dead.
We are no longer honoring what it claims was "The deal". Now it claims we are just dead weight, so we have to go.
There is another bracket of folk, as technical as any scientist, with data backed evidence showing that there is a new system, not involving profit, which we are already moving to, which promises not only complete independence of the energy of Earth, but repair of the damage done by the old system, by our species beginning to truly create, for the first time in known history, instead of net destruction.
But we have to want it, as a species, or not.
Our species can be born from dependence on depleting and destroying the energy of our planet, or not.
This is the same dilemma as faced by every living thing, at time of birth, it can choose to be born from dependence on the energy of its mother host, or egg, or not.
We can choose life, as a species, or not.
Get busy livin' or get busy dyin', this is truer than ever, but now it is being put to each of us individually, on behalf of our species.
Its either all of us or none of us.
Not understanding, or refusing to understand what nature is telling us, via the data available from formal systems Engineering studies of current events, means you will never understand what inflation is, or why the nuclear bombs are raining down, just when you see them you'll feel relief that it's all over, no regrets, it seems to me.
