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.
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 cheaper basic staples and sells LATAM more services and value-added products.
I'd rather help our Latin "cousins" get out of poverty, than having to deal with the insanity of US culture wars.
As another commenter pointed out, beef is especially interesting. On one hand EU cries about greenhouse gas and how we should eat less meat. On the other hand goes to reduce price and increase production of beef which such moves. Pure hypocrisy.
I wonder if someone will double down on checking how Brazil is protecting its rains forests? Or will it just look the other way while Europeans eat cheap food that was grown in what was rain forest very recently?
As for transport - enough of this stuff is already transported across the ocean (from LATAM but also South Africa, for example) that I doubt there will be much of a change.
Current population density isn't an issue at all, but energy is.
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.
We need on the contrary to produce less globally, but more organically, and to reduce waste and produce locally
Fortunately there's around 800kg per capita worth of food storage in the EU, so should a war break out we're not all immediately dead - just vegetarian after a period of slaughtering all the livestock that can't be fed.
From a national security perspective, it is essential to provide basic nutrition to people when international trade is disrupted. Having access to food people enjoy eating is not essential. The viability of existing agricultural businesses is not essential. The preservation of cultural traditions related to food and agriculture is not essential. And so on.
It's also important to consider where the subsidies should be directed. Here in Finland, the explicit justification for agricultural subsidies has always been the assumption that food produced in "European countries that still have a strong farming industry" might not be available during a crisis.
