And? Problems with farming and food have nothing to do with the availability of land or being able to produce enough, it is logistics and profitability or lack-there-of. Farmland utilization has been dropping for decades, which probably isn't as great a thing as some might think because it means we are more reliant on artificial fertilizer and unsustainable practices, but if we actually wanted to grow more food to eat the only barriers are ourselves and our politics and economics. There is no lack of arable land for food.
