Did you read my post? In my world, well an ideal world really, the ideal number would be 0. Ideally humans would look at what they have done, to both the planet and each other and would accept that no real good has come out of us and would accept to do one good thing by choosing to be the last generation and going extinct.
I acknowledge that it is almost impossible to request as it goes against any animal's survival instinct so if I had to pick, the smaller amount the better. Again, we serve absolutely zero purpose. There is no need for 2, 3 new humans to come out. It's a personal choice and will and ''need'' for some to feel compelled to bring in more of us BUT it benefits no one but us and it definitely doesn't benefit them (and again, ''us'' is a big word when you look at what humans do to each other on a daily basis. AIBU being the perfect example actually, without even talking about wars, genocides etc...).
Again, bring in as many kids as you want into the world, it's your kids and grand-kids who will likely have to deal with the end result of your choice to pro-create and to bring them up in a planet that has been and will continue to suffer irreversible changes and likely will bring in irreversible consequences to them. THEY will be the ones suffering, your kids, not me or you.
You CANNOT compare the consumption of your single childless friends with yours. If you have kids, you and your offsprings FAR outweight the consumptions of this one single individual making your choice, yes, more selfish than theirs. Even if they consume a lot, they didn't chose to get born, they are doing what humans do, consume resources and bring back little value, you on the other hand are doing this PLUS choosing to bring in more people to consume and bring back little value. You are ADDING to the burden. Can't you see how that makes you more selfish? Really? Plus if they remain childless their impact is limited to their lifetime (80 years or so), your choice on the other end will spread for as long as your descendant continue to procreate and bring in more kids. Centuries likely if not forever.
No my opinion wouldn't change if all of my friends stopped having kids. I love kids I have been a nanny and a teacher, kids are massive part of my life, it doesn't stop me from acknowledging that while they are cute and lovely and I love them and (selfishly!) want them to live as long as possible and be happy, it's still not the right thing and the planet would indeed be better off without them (and me!), it's a fact. it's not personal and it's what it is. I suffer more from the idea that a lot of them have had to be in lockdown for a good chunk of their life and have had to survive almost continuous natural disasters in very little time and that it's likely only the beginning for them, and what it could mean for their future than I do the idea that they could simply not have been born.
I had a miscarriage a couple of years back, it was painful but sometimes like right now I sit comforted by the knowledge that he probably did more for the planet and the world by not experiencing it than would have happened was he around to see and live through the consequences of human decisions.
I still very much think I would have been selfish had I managed to give birth to this baby, the fact that it's mine and I would have loved him and wanted him to be happy and selfishly live as long as he potentially could, wouldn't have changed that. You can love someone and still acknowledge their presence is destructive and not what's best in the bigger picture.
It's different to chose to not care about the bigger picture but then we have to acknowledge that not doing so is selfish.
