Holy cow! We’re crazy to farm livestock like this

Joanna Lumley (yes, now Purdey is an expert on global warming, too).

OK, I’m sold, let’s exterminate all the cattle on the planet. And we need to get rid of all the antelope, wildebeest, buffalo and the animals that feed off them at the same time. I think Joanna is going to need a bigger gun.

I think this is just plain stupid. Surely, any animal, in the wild, is carbon neutral? Everything is recycled all the way through to the worms and maggots at the end. Including the methane, or whatever, from their digestive systems. I think it is called an ecosystem or something like that. Or am I missing something?

The only problem comes when you adopt certain intensive farming methods, so surely the solution is not mass extinction of cattle, but to modify those practices?
