If it is a white hat operation= removing tainted food, human "food?" or dangerous food additives.
If it is a black hat operation= food shortages, increasing food prices, cause famine to cause panic, riots, chaos.
God fed people with manna, quail and water from a rock, also fed 5000 with three fish and a loaf of barley bread. TRUST GOD, and help each other. Community gardens would be very beneficial, not all people can grow food since many don't have yards, or climates suitable for growing their own food. People who own good and could donate some land in their communities or charge a small rental fee for an area to plant. 😇
