Population growth doesn't create nuclear plants, well educated people who don't have to worry about their daily needs creates nuclear plants. Our current infrastructure only supports X billion people to not live in poverty, every person you add over that X will be a miserable and thus unproductive life that still costs resources.
Sure I believe the earth can support 10 billion people who doesn't live in poverty, but that would require a lot of infrastructure that we don't yet have. Adding people before you can ensure they don't have to live a life of misery will just hurt progress, for progress it is better to have 100 people who live a good life than 1000 people who live near starvation, so the fastest way to get to 10 billion people living a well life is not to first add 10 billion people who have to live in misery.
