Tom Philpott at Gristmill is among those noting with approval that Monsanto is trying to sell off its making of recombinant bovine growth hormone (rBGH). It's an interesting issue: on the one hand there's the "yuck" factor, those who believe that interference with nature is wrong and on the other the "green" factor, those who believe efficiency is the way of the future. That is, if the hormone enables the production of more milk from the same inputs, isn't that similar to an Energy-Star appliance?
Obviously I lean more towards the efficiency side. But "lean" is the right word.
