Thousands of years of agriculture under our collective belts, and what have we learned? Sandra and Tom take a look at what we've done with our food. We love to play with it and now, it looks like our food is the worse for it. Sure, we can bring a beef cow to market in a third of the time it took in the 50s, and we get more milk from a dairy cow and a chicken takes less time to be ready for the pot, but are they better nutritionally? The answer seems to be, no. No they are not. Chickens are fattier, milk is less nutritious and our carrots. Our fighting carrots of the Second World War would mop the floor with the carrots of today. Sigh.
