The point of the climate change people is the more people you bring into this world the more people will use cars, airplanes, etc… as a result, having kids make all those problems worse. It’s not hypocritical to say « we are all participating to climate change but me giving birth to 3 new humans would lead to my own carbon footprint + those 3 humans carbon footprint + their own kids carbon footprints and grand kids etc… and so I am going to limit my carbon footprint to my own rather than bring more people in because even if I do all the bad things for the environment it will lead to a lot less carbon footprint overall than me having kids and them having kids ».
As for the imbalance between old and young. I think young people don’t fancy working hard to not be able to afford to buy a home and to still somehow struggle to pay their bills, and likely ironically not get a retirement themselves in the very end.
I think euthanasia should be legalized in most/all countries. Humans should be able to live for as long as they want and to their entire lifespan if they wish but sooo many elderly people wouldn’t pick that life for themselves. Many would have wanted to die at 84 when still having a fairly good but declining quality of life than at 104 completely unable to do the things they want to do or now with dementia. But somehow people are being shamed for not wanting kids and to add to the overpopulation problem instead of looking at ethical ways to reduce the gap between young working force population and elderly population who needs care.
Currently the system is made to force people to live for as long as possible, irrelevant of one’s will and quality of life, all while hoping young people will pick up the tab instead of maybe accept that maybe there is a reason why we initially weren’t living to 100yo naturally without technology, and while we shouldn’t think to kill people off just because they are old and/dependent we should maybe give people the ownership of their own life and accept that if people were allowed to go when they want to go, maybe there wouldn’t be such a gap in population size between people who can work and pensioners or even an overpopulation issue (as I am sure hundreds of thousands of people worldwide would pick that option today for a variety of reasons if offered and legalized.)
Somehow people think increasing birth is the solution when stopping to over extend life and control death would likely naturally partially fix the problem.
