Practically if there will be less population than Efficient and distribution of resources will not create a problem.

For example - If a Big tree ( population) have thousands of dry leaves ( distribution) coming down and getting collected nearby your house. Then you have to cut down the tree not the leaves from its branches because if you cut down the leaves it will again grow and then again it will create mess. What I meant to say is we have to see the root of the problem, not the problem.
