This is why I only grow / catch my own food or eat organic and naturally grazed food from local farms. I grow our own organic vegetables and I catch my own fish. I make sure my meats have no added hormones and are grazed feed. Once I have my own piece of land I'll be raising my own chickens for eggs and bees for honey and pollinating my vegetables.

Square Foot Gardening by Mel Bartbolomew. Anyone can grow their own organic vegetables in only 4'x4' piece of land. Its ridiculously simple and it works.
If you live by the ocean, buy a fishing rod and learn what fish run at what time of the year. I can catch buckets full of mackerel every day they're running. Clean and freeze them for FREE fish year round.
