Animal agriculture and climate change
The effects of agriculture on climate change are not something I’ve written much about, mainly because I don’t know how to evaluate the assumptions involved in assessing the effects. Different assumptions lead to different conclusions. But if we are going to develop agricultural systems that are truly sustainable, they will have to keep greenhouse gas emissions to a minimum. Yesterday’s New York Times lays out the issues pretty well. If its analysis is correct, we all need to be eating a lot less meat. In any case, this seems like a good place to start the conversation.
