It is not at all that simple. Unfortunately we are "harvesting" the "food supply" way beyond the capacity for it to actually regenerate. For various reasons, several different groups tell us that there are "sustainable" levels of "harvesting" the "food supply", but reality is that the actual sustainable and regenerative capacity of the ecosystems is far lower than what people are willing to accept. Accepting actual sustainable/regenerative levels would inevitably change things for those groups, whether it is making less profits and putting people like fisherman out of business, or that the totally out of control African and Asian populations need to be dramatically reduced or massively have their consumption repressed and immigration from low to high consumption regions reduced. Either way, people will not like it on both sides, which is why it is ultimately not solvable.
If we wanted to really solve this issue, which most people, not just here, don't really want to; we would set definitive measures like allocating to every society an equal, fixed amount of consumption (e.g., x tons of fish, grain, etc.) regardless of population size, so that the incentives would prioritized sustainable human populations too; at the very least for the out of control African and Asian continents. I would say that regardless of "color" or culture of people; even if every human looked exactly the same … it's simply not sustainable that the Asian and African populations are net increasing by at least 2 people (if one believes the questionable numbers) every single second of every single day. Meaning that by the time you have read this, there will be roughly 120 net more Asians and Africans than when you started reading this. That's simply not sustainable when they all require feeding and are increasingly demanding more and more "diverse" foods.
Personally, I actually have a theory that some of this whole "pandemic" response is part of a response to that reality, the ruling class using the opportunity to at least hit the pause button to assess where to go with this, because no matter what, the path we were heading down fast was simply not sustainable.
