Answer: It does not
Step-by-step explanation:
Even though population growth has dropped below the replacement-level fertility rate in a lot of countries, it doesn't change the fact that children are still being born.
Every child that is born has the potential to increase the population by more than 1 when they become parents so human population will still grow.
Add that to the high population growth rate of less developed countries and it is still evident that earth has a population problem.
