I want to help with my knowledge.

I want to help with my knowledge. I am an economist. Housing is a big problem and I know the solution. The solution is easy, the problem is the problem is wanted. I propose as the fastest and easiest way to end the housing problem and help the planet to decrease the population. With fewer people would stop the need for more construction. Does planet Earth need more and bigger airports or fewer inhabitants?. At some point the population will have to stop growing. So why not now?. Thank you.
