My work has also motivated me to put a lot of time into seeking out good food and to spend more money on it.
In addition to contributing to erosion, pollution, food poisoning, and the dead zone, corn requires huge amounts of fossil fuel - it takes a half gallon of fossil fuel to produce a bushel of corn.
In corn, I think I've found the key to the American food chain. If you look at a fast-food meal, a McDonald's meal, virtually all the carbon in it - and what we eat is mostly carbon - comes from corn.
Corn is an efficient way to get energy calories off the land and soybeans are an efficient way of getting protein off the land, so we've designed a food system that produces a lot of cheap corn and soybeans resulting in a lot of cheap fast food.
Perhaps more than any other, the food industry is very sensitive to consumer demand.
Fairness forces you - even when you're writing a piece highly critical of, say, genetically modified food, as I have done - to make sure you represent the other side as extensively and as accurately as you possibly can.
Plus, I love comic writing. Nothing satisfies me more than finding a funny way to phrase something.
For at the same time many people seem eager to extend the circle of our moral consideration to animals, in our factory farms and laboratories we are inflicting more suffering on more animals than at any time in history.
The things journalists should pay attention to are the issues the political leadership agrees on, rather than to their supposed antagonisms.
