you still lose people to starvation, you are living above carrying capacity.
By that definition the carrying capacity of earth is zero. No matter how few people there are on earth there will always be some scenario where some guy starves to death because he couldn't get to the other side of the valley where the food was.
We are losing about 10 million people per year to starvation, and there are close to 800 million undernourished people in the world. I am not talking about a random guy not finding his way to an opulent dinner, but about a systemic proplem.
Yes, and that systemic problem is completely unrelated to global food production. We could double production or half the population and people would still starve to death and be undernourished because we are incapable of distributing the food we have to all the people who need it.
