That is the best "proof text" for the fallacy of the concept of overpopulation. There is no rescinding of Genesis 1:28. Anyone who claims "there are too many people" is clearly out of line with Scripture. If such were possible, God would have told us.
The myth of overpopulation is a demonic deception.
The devil hates mankind, because every child conceived can go to heaven, where the devil can never again tread. It was the concept of man - the combination of an eternal soul and a physical body - with free will, that lead to satan's rebellion in the first place.
Every soul the devil prevents from being conceived is a little demonic victory against God, IMHO.
THe population of the earth is approaching 6 and a half billion last I checked. How much is enough?
