The Earth does not belong to us...

... we belong to the Earth. Yeah, I know it's a bumper sticker slogan, but is there a better way to describe how our actions are connected to and affect all the other life on the planet? Or put another way, can one better describe how our survival is dependent upon the survival of all the other life with which we share this precious Earth? I believe the acknowledgment of the interconnectedness of all life on earth, especially how it affects human beings, is the most important factor in our long term survival. Are you not concerned about the survival of the human race in the future? How about your own survival or that of your children?

Think about it. Where did the food you ate for breakfast come from? What will happen to that food source if we continue to waste, degrade and plunder the natural environment in which it was harvested? What would happen if all (or even most) of the bees in the US disappeared next year? No bees, no fruit, vegetables, nuts or grains. Think this sounds like a sci-fi apocalyptic doomsday scenario? Since 2006 in the US, commercial honey bee operators started reporting the loss of 30-90% of their hives. The bees simply disappeared and did not return to the hives, leaving the queen to starve to death. If you think this only affects honey production, you are in for a surprise. According to the Agricultural Research Service of the USDA, "About one mouthful in three in our diet directly or indirectly benefits from honey bee pollination."

Now known as colony collapse disorder, to date there is no definitive explanation for this continued honey bee die off. Some leading contenders:

• Overuse of new pesticides developed in the 1990's
• Several invasive parasites introduced to the US in the 1990's
• Higher virus and bacterial infection due to lowered bee immune systems (from unknown causes)
• Lack of pollen diversity (large monoculture plantings)
• Environmental stressors due to climate change, water pollution and habitat destruction
• Some combination of all of the above

The alarming fact is that all of those causes are from human activity (either intentional or otherwise). This is simply one example of how we are sowing the seeds of our own destruction because we are not acknowledging our dependence and interconnectedness with all other life.

If we continue to consume, degrade and destroy the resources of the earth with such reckless abandon, we will be the ones to suffer. As a dear friend of mine likes to say, "Nature bats last." If there is a massive die off of humanity, the rest of life on the planet will recover, take over and eventually restore the wastelands we will leave behind. The only suffering will be our own, of our own making. Fortunately, we can make conscious changes now to avert the worst disasters. Unfortunately, it is too late to avert them all (like global climate change which is already occurring).

Beyond the apocalyptic, fear mongering message (which I dislike, but is sometimes necessary to raise awareness), I think the hopeful message is that the alternative is not painful. Yes, we have to change our attitudes and behaviors, but for what? How about a more beautiful world filled with more plants and animals and less concrete and asphalt? More responsible use of the earth's precious resources and less waste and garbage? More healthy living environments and less pollution? More healthy people and less famine? Living in harmony with each other and the environment instead of conquering, consuming and destroying it? That doesn't sound like a sacrifice, but a world in which we would all be more happy and content. How can we turn our backs on that future?

Why Food Security Matters to You

I believe there are two aspects to food security, both of which should concern all of us. The first and probably less familiar aspect is that of security from contamination. Contamination can take many forms, from E. coli and other biological agents to pesticides to heavy metals to animal hormones to discarded pharmaceuticals. The reason I add this as a factor of food security is because contaminated food is as good as no food at all. The second aspect is simple access to fresh, healthy food. Some inner cities of our large metropolises like Chicago and Detroit contain food deserts where no grocery stores exist for many miles. The only options people in these areas have for sustenance are fast food restaurants and convenience stores that sell highly processed and packaged food products.

For those of use fortunate enough to not live in a food desert we also need to be concerned about the availability of healthy, fresh food. A quick look at how our food is produced and distributed will outline some areas for concern. In the US the average super market travel distance for fresh fruit and vegetables is between 1500 to 2500 miles. Think about this for a moment. That lettuce you are eating in your salad tonight probably traveled farther to get to your refrigerator than you did on your last vacation. So what does this have to do with food security? Since our food network is stretched so long and is so reliant on cheap fuel, the interstate highway system and an enormous fleet of trucks, it is susceptible to many kinds of disruptions.

This is most apparent during natural disasters such as hurricanes. Under normal circumstances the stock in most grocery stores becomes depleted in three days. This means three days without any truck deliveries and your local store has no more food for you to purchase. Fortunately, natural disasters are not normal circumstances. We have all seen footage of empty store shelves hours before a large hurricane is scheduled to make landfall in an area. Luckily, most truck service is restored only hours after a hurricane has passed and the stores can be restocked. Sometimes, however, that is not the case.

As most of us can remember, after hurricane Katrina, the city of New Orleans descended into anarchy and chaos within a few days without drinkable water, electricity or food supplies from the outside world. Shocked that a city in the US could fail so quickly (and appalled at the apparent lack of federal response), I drove from Chicago down to Baton Rouge, the largest nearby city where a relief effort was being staged, to help. Inside the gymnasium and sports arena at LSU the Red Cross (with no help from FEMA or any other federal agency) was staffing a small city of cots, medical services and a cafeteria to house and feed five to six thousand refugees from the flooded city 50 miles to the south. The biggest impression I took away from my experience is how fragile is our modern lifestyle.

So what does this have to do with food security? Unfortunately, hurricanes are not the only threats to our thin and delicate web of food production and distribution. Drought, spikes in fuel prices, labor disputes and strikes, failing infrastructure, economic panic (e.g. fall of 2008), resource shortages, terrorism and severe weather events can all disrupt our steady supply of fresh, healthy food. But even if none of these calamities occur, we still have to contend with the other aspect of food security, contamination.

I've been considering all of these issues for several years and the simple conclusion I can't escape is the best way to improve one's food security is to grow more of it yourself. And growing your own food has the added benefit of reducing green house gases due to current energy intensive, factory farming practices and long travel distance by truck. And can you get more fresh than eating something five minutes after it is picked from the ground?

Every home owner has some kind of yard with some amount of ornamental vegetation, depending in which area of the country you live. Most of us own a swath of grass, the stereotypical American lawn, upon which we spend an inordinate amount of our summer months to maintain. Wouldn't it be a better use of our time and resources if we replaced some of that grass to grow something we can actually eat? Now that's food for thought.

Get Closer to Your Food

No, I'm not suggesting that you snuggle up with some broccoli, a chicken breast or bag of flour. But how far did all of those items travel to your dinner table? How many gallons of diesel fuel were burned so you could eat your last meal? How much have all of us contributed to global climate change simply due to the travel cost of the food we eat? For those of us in the continental US, have you ever eaten an apple grown in New Zealand? Grapes from Chile? Strawberries from Mexico? All of these foods incur high fossil fuel emissions in order that we can eat fruit in the winter.

A common message to reduce this burden on our global climate is "eat local, eat seasonal". This is a great idea for several reasons. Not only does it reduce fossil fuel emissions but you get fresher and most of the time better tasting produce with higher vitamin content and nutritional value. But can you get more local than your backyard? Is it really possible to reduce your fossil fuel emission burden for the food you eat to nearly zero? Let's see what that might look like.

It should come as no surprise to anyone that our food is produced via biological systems. Plants do not grow in isolation. They are dependent upon a host of beneficial organisms and nutrients from nitrogen in the air to the bacteria that converts it into ammonia (nitrogen fixation) in symbiosis with some plant roots (primarily legumes), to the nitrifying soil bacteria which convert the ammonia into nitrates and nitrites which are absorbed by plants as natural fertilizer. The cycle continues as plants die and decay with the help of more kinds of bacteria and fungi which create more ammonia, nitrates and nitrites to start the cycle again. In addition, animals that eat and digest the plants (again with the help of beneficial bacteria in their digestive tract) produce more ammonia in their droppings (manure) which in turn adds to this never ending cycle.

The reason for the detailed lesson in the nitrogen cycle is to reinforce the notion that whether we want to acknowledge it or not, we and the food we eat are part of this cycle. In order for us to produce food in the most efficient manner (e.g. with the least amount of resources) we have to be both cognizant of this fact and take advantage of it to the fullest extent possible.

So what might this look like in a home garden? First, it means committing to a fully organic gardening philosophy. This is important for two reasons. First, because our goal is to reduce our reliance upon and consumption of fossil fuels. This is not possible if we buy and consume man-made fertilizers, pesticides or herbicides, most of which are either direct petroleum products or require large amounts of energy (derived from some fossil fuel) for production and transportation. Secondly, if our goal is to produce healthy food, why would we contaminate it with chemicals which in the very least have unknown health effects and in the worst case are known carcinogens or toxins (for a scare, read the label of any pesticide in your garage or garden shed).

Keeping in mind all the parts of the nitrogen cycle and our commitment to fully organic practices, a small kitchen garden should have the following components:

• Compost pile - made up of all vegetative matter collected on your property. Be wary of taking in compost or vegetative matter from other sources due to the possible contamination of persistent herbicides. Keep a small bucket under your sink and throw in all fruit and vegetable scrapes (no meat products) and add to the compost when full.
• Cover crops - nitrogen fixing plants such as clovers or hairy vetch to suppress weeds, improve soil quality and used as in-place compost when it is tilled under before planting edible crops.
• Rich soil - created by use of compost, cover crops and ample use of mulch to both hold in moisture and deter weed growth.
• Chickens - OK, this is probably optional, but consider this. Four laying hens will produce about a dozen eggs a week. In addition, let them into your garden before planting and after harvesting to eat bugs, till the soil and add fresh manure. Taking care of four hens is no more work than a dog, and few of us hesitate bringing one of them into our lives.
• Crop rotation - use a three session rotation, planting your veggies in a different bed to reduce disease and recurring pests. When selecting a crop to plant make sure it is from a different plant family than the previous crop in the same bed (e.g. broccoli, cauliflower, cabbage and Brussels sprouts are all in the family Brassica and should not be rotated in the same bed as common pests and disease afflict them all).
• Beneficial predators - encouraging or adding beneficial insects, spiders and other pest predators (e.g. birds and bats) is a low cost and low maintenance way to suppress pest species
• Pollinators - encouraging pollinators (insects, birds and bats) by planting inviting flowering plants (which don't have to be edible and add color and beauty to the garden), creating nesting sites and planting shrubs and other perennials for shelter as well as another source of food.
• Food storage - when a harvest is ready, you will probably have more to pick than you and your family can eat before the produce goes bad. Learn how to preserve fruits and veggies via canning, drying, or low energy cold storage such as a root cellar.
• Mindfulness - walk your garden daily and simply observe. Is the soil too wet or dry in some areas? How do the leaves of the different plants look as they grow? Do you notice indications of any pests or disease? Are certain plants thriving or suffering? Research problems before they become to difficult to remedy.

Don't fall into the trap that unless you grow a big garden, you won't be doing enough to make any difference. Even if you live in an apartment or condo you can grow in a window box, on a patio or even a rooftop. Start small, a few tomato plants or a few red peppers. Follow all the techniques and increase your plot over several seasons. Let your garden grow with your experience and you will see it as a source of joy and relaxation, not one of toil and labor. Anything that you grow on your own, no matter how small, will bring you closer to your food. And that is good for all of us.

Private Land Ownership

If you think about if for a second, the concept of private land ownership is a strange one. Each of us is born into this world, one that has existed for billions of years before any of us show up on the scene, and at some point in our lives we draw an arbitrary boundary around an area on the landscape and say, "This is mine." I can't think of a better example of human conceit and self importance. Yet to consider all of the cruelties inflicted, rivers of blood spilled and whole societies destroyed throughout the ages over land disputes simply boggles the mind.

I understand that land ownership is all about control of what can be done on a particular parcel and who can do it. Usually it boils down to the use of resources contained within whatever arbitrary boundary seems relevant to the parties in control. All of our conventions of law and legal transfer of ownership are simply processes we have put in place to reduce the amount of conflict related to determining who gets to decide what happens within what arbitrary boundaries. But over most of human history, the deciding factor has been who has the most lethal weapons and the biggest army.

But the issue always comes back to the use (or in most cases misuse) of natural resources. Our society, and almost all societies in the world today, are based on the concept of land ownership, either private or public. Every square inch of the surface of the earth is owned by someone. Notable exceptions are Antarctica (the only landmass on Earth that has no native human populations and is protected by international treaty) and the world's oceans, twelve nautical miles beyond shore, although there are many international treaties, disagreements and exceptions even to this simple rule.

My main observation is that even within all the rules, regulations and practices imposed on a landowner by local, regional and even international laws, overuse and sometimes outright abuse of natural resources occur across the globe. The problem is that landowners no longer are the only ones to suffer from mismanagement of their land. Most environmental problems, such as deforestation, pollution and resource depletion have regional and sometimes global consequences.

So this post is more food for thought than a recommendation for specific action. How do we raise global awareness for the consequences of resource depletion? Or maybe more to the point, how do each of us become better stewards of the land that we do own? (I touched on this issue in a previous post). No matter if that is a condo in a densely populated urban area, a 1/4 acre in a suburban sub-division or a 50 acre homestead, I'm convinced all of us can do a better job as sustainable land owners.

As a soon-to-be steward of about 5 acres in rural New Mexico, here are a few questions I will be asking myself which I think we should all consider. How can I utilize native, less resource intensive (water, fertilizer, labor) plants? What can I do to encourage more native wildlife on my property? How can I accomplish the same benefit (enjoying a beautiful landscape) with less labor and resources? For example, gas powered lawn mowers and leaf blowers are not only noisy and polluting but very inefficient compared to gas powered cars. Reducing or eliminating their use is a huge step towards sustainability.

In order to accomplish meaningful change we need to throw out old assumptions. For example, why do we assume that every house in America should be landscaped with sod (even in desert regions like Las Vegas)? Break the mold, challenge convention and replace that ocean of bland grass with more interesting and native landscaping that requires less water and maintenance. What else can you do to become a better steward of the land you own?

Nature From Within

Humans are part of nature. Whether you live in a densely populated city or on a rural farm, you live in an ecosystem that consumes natural resources and supports many organisms, both plant and animal. We cannot escape this fact, whether we acknowledge it or not. In fact humans create many unnecessary problems when we do not recognize the consequences of our actions to the environment around us.

The blinding and isolating effects of "modern" society allow humans to pretend to live outside of nature in our artificial environments. We go to great lengths quite often to isolate ourselves from the world in which we live. Just look at our sealed and air conditioned homes and cars. Cellophane wrapped, boxed, frozen, freeze dried, vacuum packed food. Earbuds, "smart" phones, iPads, wall-sized TVs and other stimulation prosthetics.

We cause the most harm to the natural environment in which we all live through our own ignorance of the debilitating consequences of our activities. What was the complete effect on the environment caused by the purchase of that chicken sandwich you had for lunch? From building and operating the concentrated animal feeding operation (CAFO) that houses 100,000+ chickens under one roof from where your chicken breast was raised. To the effect of growing the grain the chicken was feed and the water that was pumped for it to drink to the waste it excreted during its short life. How about the processing plant where it was slaughtered, butchered and packaged? How about all the diesel fuel that was burned to ship and distribute the fertilizer, pesticide and seed to grow the grain and the grain itself? How about to ship the packaged chicken to the fast food distribution center and finally to the chain restaurant where you bought it? What are the effects on the environment for all the packaging both of the chicken feed, the antibiotics it was feed, the boxes in which the packaged chicken was shipped and finally all the packaging for everything else in your sandwich like the bun, the condiments, lettuce, tomatoes, etc.

And that is just for one chicken sandwich. Every single activity in which we participate every single day of our lives has direct, yet sometimes very hidden impacts on the environment from which we cannot escape no matter how hard we try. The more we pretend that we live outside of nature, instead of within it, the more harm we do to it and ultimately to ourselves.

The Cost of Mordern Farming

Current farming practices allow humans to produce more food per acre than was even imaginable 50 years ago. However, this huge gain in food production has a tremendous cost. Not only are these practices incredibly energy intensive but they rely on many toxic herbicides and pesticides which find their way into both our food chain as well as the environment at large.

Why is this a problem? In addition to the obvious issues with ingesting toxic substances, some of these chemicals are indicated as hormone mimics which can contribute to a whole host of issues from infertility to obesity to some forms of cancer. Moreover, the amount of fossil fuels required to grow a pound of food accounts for almost half of all costs considering the production, transportation and distribution of everything from the pesticides, to fertilizer to seed applied to an acre of a crop. Add in the tilling, plowing, seeding, watering, harvesting, processing, packaging and transporting of the crop itself and you can see that humans pay a very heavy price in energy consumption to achieve the fantastic levels of food production we currently enjoy.

But that is not the only cost incurred by our factory farming and mass food production practices. Most agriculture in the U.S. is now irrigated, and a significant amount by non-renewable aquifers like the Ogallala in the central plains. This one aquifer irrigates 30% of all irrigated land in the U.S. By the latest estimates, the deepest wells will start running dry in 25 - 30 years at current pumping rates. This is in an area that is already semi-arid and supported only a fraction of the amount of current agriculture before the massive pumping and irrigation from the aquifer.

Another hidden cost is the effect of both fertilizer and livestock excrement runoff into our nation's waterways. The excess nitrogen and other nutrients in this runoff causes excessive algae and bacterial blooms in rivers, streams and eventually the ocean. These blooms deprive the waterways of oxygen resulting in the die-off of whole ecosystems, from the micro-organisms all the way up the food chain to the fish and the mammal and bird predators who eat the fish.

Finally, in return for this incredible production of food, we have given up the two most important aspects of the food itself; its taste and nutritional value. Almost all fruits and vegetable hybrids sold in grocery stores today are bred for neither their taste nor their nutrient value but for their shelf life, color and hardiness for shipping and transport from the field to the store aisle. Unfortunately, taste and nutritional value are usually sacrificed for these other attributes. Like the large, beautiful rose hybird that has not even a hint of fragrance left, our fresh fruit and vegetables pale in taste and nutritional value compared to that which our grandparent's generation were accustomed.

Ultimately, the biggest problem with all of these practices is that they are not sustainable. Not just because we are using up all the water in the aquifers or all the oil to power the farm machinery and trucks, but the arable land whose topsoil is eroding away due to the very practices that squeeze so much food out of each and every acre. We have to try something different before we are forced to do so by the constraint of our limited resources.
