How do you feel about the climate change impact due to red meat production? I can't really imagine any way to decrease that other than drastically decreasing red meat consumption.

I honestly haven't looked into it. I have heard some people say the idea that it's vastly more polluting than farming (farming what exactly?) is not entirely accurate. So there is at least some amount of controversy.

I know that in my country (Belgium), cattle is often fed the excess and/or unused part of some local productions (beetroot, hay from the farm ...). So that actually sounds useful to prevent waste.
