I've been thinking about this thread and how all the other threads about doing things for the environment don't get such an emotional response.
Everyone knows that you're supposed to try not to fly or to drive a massive gas guzzler or buy shit loads of clothes and that's fine, but the minute anyone mentions meat and dairy consumption, people are lining up to tell you why it's not true or - better yet - to tell you why it doesn't apply to them. You don't really get that on the other environmental threads.
And then they try to 'other' the people who are trying to do their bit by calling them all sorts of nicknames. 'They eat mostly vegetables. They're not like me.'
I suppose I can understand the emotional response, some people really like meat, I get it. But the easiest way to influence what is grown in the fields, what the BPS applies to, for example, is to eat less meat and dairy - any kind of meat and dairy - so that farmers are encouraged to grow other crops (and yes, I am aware of the Welsh hill farmer argument, thank you, but it only applies to a very small amount of actual grazed land).
