Can mutants be infertile? Or will they IVF all their children?
People are supposed to die for a reason. I think its highly unethical that they are essentially playing God here, not really thinking of the ramifications
Why let mutants go extinct?
After all the severe reductions in population (Genosha, Decimation, the Terrigen mists), I'm glad they decided to say fuck you to the world and do what they had to do.
This basically makes them more similar to the Eternals. This might be deliberate as the rumor is that in MCU mutants will be created by Eternals.
In the short term it is not a problem at all. Krakoa seems able to produce all the organic matter it wants (So, unlimited food), grow whatever is necessary to house more mutants (houses) and can distribute the goods instantly and without cost (Teleportation).
Moreover, if Krakoa is not breaking the conservation of matter and is consuming CO2 to carry out photosynthesis, then its simple existence helps against climate change.
This right here. We don't have a space problem, we have a problem with those who control real estate and resources. America wastes 40% of its food supply but still has a poverty problem. We have tech bros buying up homes and apartments for one resident but originally housed a family of five.
