My Saudi Arabian breakfast



by Chad Heeter, from Tomdispatch.com, posted on Energy Bulletin.



For decades, scientists have calculated how much fossil fuel goes into our food by measuring the amount of energy consumed in growing, packing, shipping, consuming, and finally disposing of it. The "caloric input" of fossil fuel is then compared to the energy available in the edible product, the "caloric output."

What they've discovered is astonishing. According to researchers at the University of Michigan's Center for Sustainable Agriculture, an average of over seven calories of fossil fuel is burned up for every calorie of energy we get from our food. This means that in eating my 400 calorie breakfast, I will, in effect, have "consumed" 2,800 calories of fossil-fuel energy. (Some researchers claim the ratio to be as high as ten to one.)

But this is only an average. My cup of coffee gives me only a few calories of energy, but to process just one pound of coffee requires over 8,000 calories of fossil-fuel energy -- the equivalent energy found in nearly a quart of crude oil, 30 cubic feet of natural gas, or around two and a half pounds of coal.

Why the era of cheap food is over

Image
Christian Science Monitor Food prices worldwide hit record highs in 2006, and all the signs are that they will go on rising this year, and for the foreseeable future. The era of cheap food, the experts say, is over and we are going to have to get used to it. This is easier said than done for millions around the world, as evidenced by protests in Mexico over the cost of corn tortillas, and in Italy last September about the price of (wheat) pasta. Staff writer Peter Ford looks at why. Read more....

Climate Confusion: Who Wins?

Image
by Michael O'Brien Climate change is the biggest challenge we face as a humans. Any serious student who analyses the information recognizes that the overwhelming consensus from scientists is that we have a very small period of time in which our efforts will have a positive impact for our planet and our children's future. For the past 10 years or so, there has been rigorous debate both by the scientific community and in the press about climate change. The debate is over, the issues have been discussed and now is the time for us to take responsibility for our future. It is fascinating to watch the media feel the need to present the “other side” of this issue when there is discourse about climate change. My guess is that they feel vulnerable from the vocal skeptics or right wing talk show hosts so they include a dwindling number of scientists or spokespeople who argue against human causation. It seems there is an inordinate amount of air time devoted to this topic in proportion
