Recently, many commodity prices have gone through the roof. You don’t have to look any further than the gas station to see the effects of $110 for a barrel of oil. A visit to the grocery store will quickly reveal that prices are also jumping for corn and wheat, as well as chicken, pork, and beef. The high price of transporting food (as well as the secondary effects of corn being diverted for ethanol production) is directly tied to high oil costs, and these rising food costs are creating serious problems for the working poor.

Even if you’re a model of self reliance and walk everywhere while growing your own food without chemical fertilizer, try this on for size – increased worldwide demand is causing a coal shortage. Since about 50% of the US electric grid relies on coal power plants, this means that rising coal costs are likely to cause rising electric bills (and/or increasing outages). That will affect the cost of green power purchased on the open market too – which makes solar panels look a lot more attractive (more marginal benefit from power savings and higher resale prices on grid tie-ins). Always look on the bright side!

When governments talk about fighting global warming, they put a lot of emphasis on reducing industrial emissions. But, agriculture is responsible for a surprisingly large share of the gases that cause climate change. By some estimates, emissions from fertilizer, animals, and farm equipment account for about 20% of all global warming gases.
Overuse of synthetic fertilizers is a major problem because some of the chemicals in these fertilizers trap heat better than Carbon Dioxide. For instance, Nitrous Oxide can retain 300 times as much heat as CO2. There are many superior organic alternatives, but these account for only a fraction of the fertilizers used today.
Farm animals are another major source of global warming gases. As cows, goats, and sheep digest food, they release a high volume of methane. Cows are responsible for about 75% of all methane made by farm animals. That’s another potent gas behind global warming – Methane is about 25 times better at trapping heat than CO2.
It may be possible to reduce these emissions with big, sweeping government policy. But, if you want to make a difference, change starts in the grocery aisle. The next time you go to the grocery store, consider produce that’s raised with organic fertilizer and leave those slabs of prime rib in the grocer’s freezer. Your body will thank you, and you can breathe easier too!
