How do people afford food when they don’t live in a place that can grow it? How do we ensure we can continue to grow food when we are so dependent on chemicals to do so? How does a developing country support agriculture without the huge subsidies currently required in developed nations? How do you educate 8 billion people on how to properly get the nutrients they need from new sources of food? How do convince society that GMOs aren’t bad?
Almost all of those are just straight up the same problems that already exist in the current system though?
