American farmers produced 600 more calories per person per day in 2000 than they did in 1980.

...There's a lot of money in the Western diet. The more you process any food, the more profitable it becomes. The healthcare industry makes more money treating chronic diseases (which account for three quarters of the $2 trillion plus we spend each year on health care in this country) than preventing them.

One of the skills of a journalist, though, is to find people who can teach him what he needs to know. So instead of taking courses, I've been very lucky in that I found teachers - scientists, especially - who were willing to teach me what I needed to know, whether it was about genetically modified crops or how photosynthesis works, and so on.
