I may have a vested interest in the person giving the lecture (she's my life partner), but the subject matter of the lecture given by Mia MacDonald, Executive Director of Brighter Green, at a recent Climate Week NYC conference, is very important. Her talk offers the clearest exposition I've seen in a while of how we're going to have to grapple with the issue of intensive animal agriculture if we're going to deal seriously with the challenges of climate change. Moreover, we need to do this on a worldwide scale, and not simply here in the United States, although as Mia states: The example we set matters.
