We'd all eat real food, not attractively-packaged industrial waste. I'm all for recycling, using every possible bit of a resource, but do you really need to eat all that high-fructose corn-syrup? No, you do not. Let's turn it all into ethanol to run our cars. Fructose? Here, have an orange. Corn? Corn on the cob, roasted on the grill, beats granola bars any day of the week. Syrup? Mmmmmm, maple trees.
Food would be locally grown and consumed as much as possible.
Not shipping food long distances means that we use less fuel and emit less pollution bringing it to market. Not that I want to discourage trade. Trade is good. Apple trees, maple trees, grapes, wheat: these don't grow happily down here in the subtropics. I'll happily trade you some oranges, mangoes, papayas, and avocadoes for some apples, maple syrup, a jug of wine, and the makings of a loaf of good French bread.
Small local farms are one form of small business. Small businesses are good for the communities they serve and good for the people who run them. More on businesses in another section.
Food would be organically produced as much as possible. The regular and profligate us of pesticides and herbicides hasn't cut down on crop losses enough to justify that much use. Fertilizers have significantly increased the yield per acre for a lot of crops, but the micronutrient content [vitamins and minerals] of much of our produce is about half what it was 50 years ago. Now you need to eat twice as much food to get the same amount of nutrition. No wonder we're all so fat.
Food animals would be grown humanely. Like your bacon and eggs? With a glass of milk, maybe? Read about factory farms. Visit one. More on factory farming in another post on another day.
