Listeria and the food system

Tuesday, August 26th, 2008

The ongoing listeriosis outbreak in Canada is evidence of how broken out primary food system is, particularly insofar as meat is concerned. Producing billions of clones in packed conditions is dangerous enough, particularly if you simultaneously marinate them in growth hormones and antibiotics. Marrying that with a food system where every step of the production [...]

This chart demonstrates one characteristic of a changing energy return on investment (EROI). This is the ratio between how much energy is takes you to produce or acquire an energy source (such as oil, natural gas, biofuel, or hydrogen) and the amount of energy contained within it. This graph relates to a hypothetical oil field [...]

Moral relevance of the ‘dash to gas’

Friday, August 22nd, 2008

Between 1990 and the present, a significant reduction in European greenhouse gas (GHG) emissions took place because coal based electricity generation was replaced by natural gas plants. Here’s the big question: should that switch be considered an act of climatic virtue on the part of the European states, and thus be taken into account when [...]
