All the good dirt

Yesterday, I was pleasantly surprised to find an article titled "The Future of Dirt" on the front page of the Ideas section of the Boston Sunday Globe. Yet another sign that the rest of the world is starting to wake up. I can't remember the last time I looked at the Sunday paper and got that really happy feeling just because they are paying attention to something so fundamentally important.

For far too long has our society looked at dirt as something BAD, not something vital. All those vitamins & minerals that we need to live on come from dirt. Think about it. All your veggies contain what you need to survive because it draws them up from the soil. Unless, of course, we're talking about meat - but where do the cows get their nutrients which they then pass up to us? From the grass they graze (if they are so lucky) or from the grain that comes from, yes, yet more soil. A little thing called the food web - perhaps this is bringing back memories of a teacher & a chalkboard? It's a pretty basic concept, and we can't engineer our way out of it.

When we talk about something being "bad" we call it "dirty". When we talked about something messy (like my house), we call it "dirty." Makes it hard to realize consciously how very important good "dirt" is when we are giving it bad connotations all the time. But we can't live without. Cannot.

So what's going on with our soil? It's eroding. We are breaking down its natural structure and it's getting blown away, eroded by heavy rain, or rendered useless via poisoning. How? Heavy tilling, for one, breaks down the physical structure of soil, exposes more of the soil to the air (thereby releasing from the soil carbon dioxide & nitrous oxide - greenhouse gasses - into the atmosphere), and dries it out. Then it rains, or it gets windy, and it blows away. We over plant it, and we plant the same damn crops on it year after year (as in a factory farm growing corn for feed or biofuels), which sucks all the nutrients out of the soil, and leaves the soil prone to a pest infestation for that particular crop. So what then? We fertilize the soil heavily, and over time, the soil becomes salty and laden with petrochemicals. We heavily apply pesticides, which also accumulate in the soil, and prevent the soil critters (the good ones) from doing their job, and the soil further looses its structure. Over time, we might as well be trying to grow that corn in a sandbox for all the nutritional value left in it. (Surprise - you can't grow much in a sandbox).

Have you SEEN the pictures of how muddy the Mississippi River is (or perhaps with your own eyes)? Where do you think all that mud comes from? It's from our farm lands, our suburban areas, our urban run off. It's filling up the Gulf of Mexico and is creating "dead zones" where fish and other sea life cannot live.

The article mentioned above touched on the Farm Bill (which appears to be completely broken and tailored specifically to the needs of the factory farm and big agri-business, yet the masses don't care & couldn't be bothered), which while giving subsidies to large scale farms growing commodities like wheat and corn, but does not do a damn thing for farms practicing good soil conservation - like rotating their crops with alfalfa or soybeans or beans, which fix nitrogen INTO the soil as they grow.

How big of a problem is this? Even I was unaware of how BIG of an issue this is (or perhaps I had merely forgotten). It is estimated (in the globe article) that by 2050, people will have to survive (on average) on less than 1/10th of an acre per person of agricultural land. That is a downright scary picture, and should be keeping you up at night. We've already destroyed so much of our soil. In the northeast, we are lucky enough to live in a "stable" soil region (but our growing seasons is relatively short, and thus not well suited to large scale production agriculture). But most of the US, and most of the inhabited world live in areas that are defined as "degraded" or "very degraded". The deserts are spreading.

According to the wiki, an area of fertile soil the size of Ukraine is lost every year because of drought, deforestation, and climate change. In Africa, by 2025, they will only be able to feed 25% of it's population. The starvation, increased food costs, and rioting that we are seeing now are likely only just beginning.

This isn't a new idea or a new issue. But soil erosion is a long-term issue, not easily dealt with through temporary legislation or in just a few years of farming practice, and in general, humans have really short attention spans. It takes a great many many years to build up good soil. You can't hurry perfection.

We've all heard the current rumblings about the recession, and even perhaps a large scale depression. Remember the last major US depression? What was also occurring at that time? The dust bowl. Here's a great old-time informational video like you would have seen in the fourth grade, complete with warbly music. The wiki, as usual, has a lot of information spelled out for you.

During Roosevelt's 100 first days of his presidency, he started a major campaign to restore ecological balance in the U.S. It would be lovely to have a new president capable of such sweeping reform, but I am not holding my breath, and I think it is likely our very survival is going to be left up to individual citizens who are well informed. Which is why I write this blog (even though I'm pretty sure no one reads it) - just on the off chance that someone, somewhere, runs across it (possibly while looking for something else) and goes off to figure things out for themselves.
