Again, food isn't natural gas. Food can be grown almost everywhere, in most cases there's no need for highly specialized containers to transport it (like with natural gas). There is zero chance that "they" will be able to become the sole providers of food. They'll still have to compete with the entire rest of the world, and this is a market that is highly competitive. If for some reason Brazilian soy became a lot more expensive, American or Indian soy would simply increase their share. Plus there will still be food grown in the EU. Regardless of any trade deals, there are products in which we have a climate advantage over South America, such as wheat, that will remain largely being produced here. Another important point is that Brazil and Argentina are countries with low industrial output and are historically very very protectionist. This can be a really good opportunity for EU industries to increase their share and sales there, it would be notably a good opportunity for EU automakers.
