The problem is, that the world population still grows very fast. See https://upload.wikimedia.org/wikipedia/en/thumb/3/3a/Human_population_growth_from_1800_to_2000.png/1024px-Human_population_growth_from_1800_to_2000.png

So we need MORE food, not less. What´s Obama´s plan to feed the world? Gen manipulated food?

I think, we first have to solve the problem overpopulation. Then we can think about establishing marine nation monuments.

I am ready to help.
