It is better that some humans survive past 2100AD than no humans survive past 2100AD

 How does the human race survive this century without going extinct?

This is the trillion dollar question for all mankind to solve at present.

It is "lifeboat theory" in action once again.

In some ways overpopulation combined with Global Climate chnage is solving this problem during this century too.

The same thing driving humans extinct (along with most other species too) at present is:

OVERPOPULATION.

So, unless Global Climate change significantly reduces human populations on earth everyone (every human being is likely to go extinct this century or the next.

So, randomly, fires from droughts (like in the western United States). Flooding (like in Central and Eastern U.S. and China and Europe) will significantly reduce human populations in areas around the world.

Places with more natural resources and democratically elected governments will tend to survive better than autocratic ones too.

Why is this?

Democratically elected governments are ruled bottom up from grass roots so this allows new ideas of how to survive to arise fast enough for more people to survive.

Autocratic governments tend to ONLY serve the needs of the leadership of that country while the common people die at random willy nilly without any sense or reason.

So, democracies will tend to survive while Autocracies will collapse like Russia may collapse if Putin dies. The same thing could happen to China if Xi has a mental or physical breakdown to or is assassinated by his people.

So, the ONLY forms of government who might actually solve the problems coming quicker and quicker upon all life on earth are democratically elected governments.

One could also say that Putin's attack on Ukraine is suicidal not only for Russia but also for the world and himself. Why?

Because the thinking that went into this attack was very retro sort of like something from the Victorian era and World War I or something like that or maybe even a Hitler or Stalin kind of thinking that is counterproductive to the survival of life on earth (all life).

However, I like Descartes, the philosopher's saying because I find it true everywhere on earth.

"There is nothing so bad that no good may come of it and

there is nothing so good that no bad may come of it"

In some ways his statement is non-dualism in action everywhere on earth and beyond.
