Stop using livestock in agriculture? What do you mean?

CO2 emissions for producing enough food to feed someone on a meat-based diet are significantly greater than on a vegetarian diet.

I may be wrong but I think the vegetarian diet needs to be close to vegan (or at least dairy free) to have a major impact though as cattle are a significant part of the issue.

Livestock produce methane which is a greenhouse gas and contributes significantly to global warming.

Tyrannosaurs is basically right - get rid of cattle sheep and pigs (plus assoc others) from our food chain. India has hundreds of millions of people living like this today so it's a viable cultural and agricultural option

It's also more or less guaranteed to slash co2 to the bone, fix enourmous run-on problems and help trade

And frankly will never happen until after we live on mars on a vegan diet and so make it cool and desirable

Basically mandatory vegetarianism?

You will be forced to live on a low cost healthy diet that will extend your lifespan by an average of ten years while at the same time saving the planet from ecological meltdown and the consequent loss of millions of lives.

The Nanny State. It's crap isn't it :-)

I'm not sure if you're being sarcastic, but I've been a vegetarian and absolutely hated every minute of it. I love eating meat too much and its substitutes aren't comparable! If I had to cut dairy out too (no butter?!) I'd just stop enjoying food.
