Methane emissions, I assume. (Solvable with 2% seaweed in the diet)

Also possibly rainforest destruction for crops, but I'm not as sure about that.

Rainforest in Argentina?

Argentina beef are raised in pasture. About as eco friendly as it gets. Converting pasture to row crops is far more devastating to the environment (topsoil loss, GHG emissions from loss of biomatter in topsoil, fossil fuel derived fertiliser and more.)

Absolutely nothing it is just European farmers crying. As if the EU doesn't already spend billions on farming subsidies.

Even if WW3 breaks out we can turn all of Europe into a vegetable garden in less than a year- the UK did this in 1940. Nobody is going to starve FFS.

That’s a pretty bold claim. I think people who want to eat need to be comfortable producing their own food.

Being utterly reliant on, say, the U.S. means ultimately the U.S. will tell you what to do.
