Is it just a coincidence that as the portion of our income spent on food has declined, spending on health care has soared? In 1960 Americans spent 17.5 percent of their income on food and 5.2 percent of national income on health care. Since then, those numbers have flipped: Spending on food has fallen to 9.9 percent, while spending on heath care has climbed to 16 percent of national income. I have to think that by spending a little more on healthier food we could reduce the amount we have to spend on heath care.
Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.
Once you introduce the issue to young people and suggest to them that they have the ability to vote with their forks, either by positively going for certain kinds of foods or rejecting other kinds of foods, they realize that this is a responsibility and an opportunity to shape the world a little bit by their own choices.
To put it bluntly, we now need to reverse course. We need more highly skilled small farmers in more places all across America - not as a matter of nostalgia for the agrarian past but as a matter of national security. For nations that lose the ability to substantially feed themselves will find themselves as gravely compromised in their international dealings as nations that depend on foreign sources of oil presently do. But while there are alternatives to oil, there are no alternatives to food.
