Extremely not-fun fact: collectively, humanity currently produces more than enough food for every person. But a huge part of it is either wasted or inaccessible by people that need them, which usually results in them not going to anyone and being wasted, which is why we still have food scarcity.
More crops go to feed in animal agriculture, than crops to humans. And farmers tend to monocrop instead of utilising all the possible crops that would do well in that environment. (Retooling, investment, skills, time, industry experts, …)
