On the contrary, this will fix the population issue. Birth rates are going down.
Sorry, but I don't think there's any 'population issue'. There's nothing wrong if global human population is lower than nowadays.
No? Western countries are below the replacement rate. Basically ageing out of existence. But you think there is no problem.
it's perfectly normal for ecosystems near carrying capacity to taper off population growth (there's increasingly more conflicts, competition for resources, etc), it means the population number will be stable, not that it will necessarily drop by much
