How To Make Earth's Population Sustainable?

[HiddenObserver]

Is overpopulation really a problem.

The population of the planet (both humans and animals) is kept in check by food supply. If the population outgrows the food supply then the excess population will die off.

I don't think there is such a thing as an unsustainable population (one that would result in the extinction of the entire human race)

The only problem is that the more people that exist the worse off quality of life for each person due to the supply and demand limitations.

If the population does get too high, reducing the quality of life for individuals, then the only controllable solution is to enforce a one child law.

Any attempt to reduce the population with violence will cause resistance, starting a war and if the choice on who lives and dies is not randomised, who would you trust to make that decision (assuming you could not nominate yourself).

I believe that a WCL will become popular when the individuals notice that there QoL is slowly improving.
