Slight point of correction:Not if you factor the oceans in.
The sea provides the biggest source of wild or domestic protein in the world. Each year some 70 to 75 million tons of fish are caught in the ocean. Of this amount around 29 million tons is for human consumption. The global fish production exceeds that of cattle, sheep, poultry or eggs.
SOURCE
It could've been a sustainable source of protein had over-fishing not occurred and destroyed biodiversity in the oceans, leaving only the fish that are riddled with toxins.
Dozens and dozens of aquatic species that were food sources (and dozens of sub-species underneath them) have gone full-blown extinct in just the past 100 years. And, Worldwide, 90% of the stocks of large predatory fish, such as sharks, tuna, marlin, and swordfish are gone compared to their levels 70 years ago. It stands to reason, you let a species higher up in the food chain go extinct, it has impacts all the way down the food chain.
"Cast some more nets in the ocean" isn't a good plan if we decide to get the population of humans over 9 billion.
It's not helping that we have major G8 countries (who are looked to as world leaders) rejecting things like GMOs and lab grown meat (which would be an absolute necessity if we were to support 9+ billion people...unless, that is, we want to force everyone into veganism and just give people b12 and iron supplements to make up for what they're not getting in their diet)
