> Farming is already incredibly subsidized in the EU As it should be if we don't want to wake up one fine day in the middle of a global war with no food supply because of a naval blockade and have our children starve to death.
Most of Europe has long reached a population density that makes it effectively impossible to achieve self-sufficiency, so this argument is pointless. This is going to be a good agreement if it is policed well enough that Mercosur countries are effectively forced to raise their food-production standards (because accepting imports doesn't automatically mean they can ignore regulations on suitability). Europe gets cheap…
The problem is rather the inputs, mainly from mineral sources, used for the production and imported from countries such as Morocco or Russia (before the war). Mercosur doesn't solve any of those problems, and will decrease the EU food autonomy as farms will disappear due to the LATAM dumping.
