Interesting piece over on Maribo about the way that flooding in the Midwestern US could lead to a big increase in the size of the dead zone in the Gulf of Mexico. This is caused each year when excess fertiliser is washed out of farmland along the Mississippi, flows into the gulf and feeds algae which grow quickly taking oxygen out of the water. Sounds nasty, but if the algae were concentrated enough, wouldn’t it be possible to make a virtue out of disaster by harvesting the alge and taking the biofuel out of it?
Gulf of Mexico deadzone all bad for biofuels?
