Synchronize global population growth and consumption of fishery products

It is common knowledge, we will face the global population growth. Until 2050, that will be 9.3 billion people on the earth. From this fact, we shall think about the food first, can the blessings of nature satisfy our hunger? If not, we must manage to produce food for ourselves. And the following data show that the global population growth and the consumption of fishery products are synchronize. So we must find a way not for capture the limited the blessings of the nature but for improving the agriculture and aquaculture more sustainably and effectively. Because if we place stress on nature, the ecological balances are very easy to fail. I think RAS is the one in the aquaculture and the hydroponics in the agriculture is same.
