Last month, our family held its sixty-first annual family reunion. It’s a chance to talk with a number of my cousins who have been farmers in that area all their lives. When I remarked about how lush and beautiful the corn looked, I learned a lot about just how precarious our food supply is. It is almost entirely dependent on vast quantities of fertilizer and diesel fuel to work the land and to irrigate it.

The situation varies, of course, depending on the type of soil found in different parts of the country. The ideal combination of local climate and fertile, well-drained soil is really quite rare. The reason that the world’s farmers are able to feed a huge and rapidly growing population is the enormous input per acre, of fuel, fertilizer, pesticides and herbicides. Much of today’s farmland is not a whole lot more than a growing medium to which water and nutrients are added – similar to hydroponics.

I will also point out here that we haven’t even touched on the complex system of transporting and delivering that food from the farm to your table. That is even more fragile than the agriculture system, with its near-total dependency on a functioning financial system, available credit, just-in-time ordering system, trucking system, and a coordinating system totally dependent upon the Internet.

There are plenty of exceptions, of course, but the fact remains that without the continuous flow of cheap diesel fuel, irrigation water, fertilizer, herbicides, and pesticides, the food available to the consumer would be a tiny fraction of what is needed. Proponents of organic farming point to that as the solution; however, there simply isn’t enough organic matter available nor is there a high enough yield for organic farming to even approach the quantity of food needed. (I’m a big fan of organic gardening, but the issue here is one of scale rather than method.)

If you’re looking for a solution to the overall problem, I’m afraid that there is none. Mankind has grown completely dependent on highly mechanized, high-input farming to feed the population. There is simply no getting around that – as a wide scale issue, anyway. On an individual scale, it is a different story. Growing and producing a portion of our own food for our own family is something that we can all do. Very few will be able to produce more than a token amount of their food to begin with, but it is a learning process. When the day comes that our complex food system no longer functions, make sure that you have the skills and the tools to feed your family.
