The rich and famous celebrities are asking to have more kids because they will need these cells to run their factory and sell product services. Economy needs to grow every year only for them.
Climate crisis also going to be extremely cruel to all species and these kids have to suffer the consequences of all the previous humans. Bringing them here is way too selfish. Even IPCC report was watered down.
