Yesterday we spoke to Professor Ralph Sims about rising global meat consumption and the harm it could be doing both to the environment and to the humans who're eating it.
A Waikato beef farmer who reckons this discussion is a bit more nuanced than that wrote to us asking for a few minutes to talk about how cows can actually help the environment.
So today Colin Brown joins the programme to chat about modern farming practices, and how beef cattle, farmed the right way, can contain emissions and stave off desertification.
