| > every person has a purpose, nobody is superfluous or redundant. > That’s a tragedy not just for Nicky, but for the rest of us, too. There’s a hole in the ecosystem where Nicky should be: there’s a hospital she should be running, or seventh-graders she should be teaching, or pizzas she should be delivering underwater. Wherever that hole is, everything else will be a little off-balance until Nicky fills it. Some interesting implications of this: 1. Any children you have, would be fulfilling a purpose in the world 2. If you decide not to have that child, you are depriving the world and everyone else of a person who would otherwise fulfill that purpose 3. Recall that no one is superfluous or redundant. So by depriving the world of a person who can fulfill that purpose, you are guaranteeing that the purpose will never be adequately fulfilled 4. The above applies no matter how many children you've already had. Already had 10 children and decided not to have a 11th? Man, you just created a Nicky-sized hole in the ecosystem. Now the whole world will be off-balance because of your tragic decision 5. So yeah, if you don't want the world to be off-balance, you better get out there and have as many kids as humanly possible |
By having more children, you contribute to more people fulfilling their purposes in the future, but this is true only to the point where resources would become too scarce when divided between the niches.
I would guess that in the future, the Earth could sustain maybe double its current population, due to much more efficient resource utilisation and extraction, relieving the demand on these resources, and the large number of people who would prefer to live in cities, reducing the demand on land. But the Earth could not sustain such a growth of its population immediately; we need time to let society and technology improve and adapt.
