Can't really take issue with any of that.
I think there's a big problem with people not caring how the meat gets to their table, they're quite happy not to give it a second thought. Which is probably also why people are happy enough to chuck food away, they've not been in a situation where food has been at a premium.
Also, if people knew the provenance of the burgers and hot dogs they were eating at McDonald's/ the cinema etc they'd probably puke it up on the spot. Alternatively, if people were told they could eat as much meat as they liked, but they had to slaughter their own animals, then you'd probably see rates of vegitarianism soaring.
As far as I'm aware, the human body was only designed to eat a modicum of meat, so I think we should all be eating less anyway. If we all regarded meat as a treat, rather than a disposable product that's 2-a-penny, and concentrated on a healthy diet then half of these problems would disappear. Dare I say it, the NHS would probably be grateful as well?
And I think I read somewhere that the optimum population of the UK was 30 million.
