Meat Ban Agenda: 'Save the Planet' by Controlling Your Diet and Land Use?

Climate zealot explains why meat should be banned, to "save the planet":

"Meat is responsible for about 20% of greenhouse gases, which is more than all transportation together. And the greenhouse gas emissions from animal-based foods are about twice that of plant-based foods."

"And if you then look at land use, it's very inefficient because 83% of all agricultural land produces only 18% of our calories. So if the whole world went plant-based, then we would cut out land use by 75%"
