Governments are being warned that a mass move to a vegan diet – without meat or animal products – is imperative for the survival of humanity, RNZ reports. Vegan Society Aotearoa spokesperson Claire Insley said humans have six years to make large cuts in emissions or the planet will blow past the 1.5 degrees of warming beyond which there are catastrophic consequences. “Diet is something that you can change really easily, really quickly, you don’t need any new technology for it,” Insley said, adding far more people can be fed with plants per acre than by animal farming.
