Re: "The rest of us should get by on beans and lentils -
it's healthier for us and the environment."
I realise of course that you were being satirical, however there are those who actually do believe that it would be better for the environment. It would in fact require a huge extension of arable monoculture farming right across the face of the planet in order to do this. The irony of the vegan position is that it would do massive damage to the earth's ecosystem if we all dropped eating meat.
