I doubt overpopulation will be a real issue.

This would multiply our available food and water supply by a factor that I don't know, but it's likely going to be large given your infographic. Once we only need a handful of animals for their tissue to grow our meat in labs we'll also need much less water/crops to feed them, and thus have more of everything to ourselves.
A bigger issue is people with the foresight of a goldfish procreating endlessly.
