Most beef in the EU is a byproduct of the dairy industry. Beef meat comes from culled dairy cows, and a lot of production is done on land that isn't suitable for other uses (mountains, for instance). The EU has also the highest norms in the world regarding food production, and they are tightly enforced, unlike LATAM where a lot of cattle is grazed on deforested land with no regulation regarding chemicals.

What you are saying is very misleading if not plain false.
