Let's put a few facts forward.
1) Climate change is unlikely to end the human race - it may end lots of human lives but that is not the same as ending the human race - so current population about 7.7 billion - 1% of that is 7.7 million - so if climate change wipes out 99% of the population there is still enough people to repopulate the world.
2) Ultimately the earth is a closed ecology - yes it is a very big one but if the population keeps rising then the collapse is inevitable as you can only recycle things so many times - so there needs to be population control or to put it another way someone needs to play god if Greta is to get her way.
3) As has been stated before the sun will become a red giant in 4.5 billion years and that will wipe out all life on earth.
4) So if the human race is to avoid extinction then we really need to get out there and colonise the rest of the universe.
You may say that 4.5 billion year is a long time - it is and it also assumes no other event completely threatens the earth - however if we do not work towards a solution I would imagine the Greta Thunbergs of 4.5 billion years into the future are going to be fooking livid we knew the sun would become a red giant and we did nothing about it.
