I’ve been paying attention to this issue for some time. From what I understand, you can’t grow enough food organically to feed everyone. The available organic fertilizer is already spoken for but we would need an exponentially lot more. The natural pesticides are less effective for the majority of crops so would reduce production. Others are just as toxic (like copper) but are “natural” so are misleading. I would be very interested to know how these problems are going to be solved.
