Most importantly, Europe needs more trading partners after having lost Russia and now losing the United States. Second, I am happy about German (I suspect it's similar in other EU countries) farmers largely supporting the far-right getting a taste of a world without protectionism and regulations. Finally, I hope for lower grocery prices, not only for myself, but also because it makes the whole social situation less explosive.
Fair trade yes. Unfair trade no. And Mercosur is COMPLETELY unfair to European farmers. It imposes higher standards - and thus costs - on European farmers, while allowing South American farmers to produce with lower quality and adding forbidden substances to grow crops faster - and cheaper.
This is a common meme but wrong.
The imported goods are subject to the same restrictions as those produced within EU.
What hurts EU farmers the most is the big supermarket cartel that controls prices and pushes farmers to produce more and more cheaply (and consumers that react extremely sensitive to every price increase, but that’s a more inconvenient truth)
Definition of a cartel is a combination of independent commercial or industrial enterprises designed to limit competition or fix prices - it can be a cartel that basically oppresses farmers and have low consumer prices as result
On average, South American farmers use 2-3 times more pesticides than farmers in Europe. 2-3 times more would be illegal in Europe, but is allowed as part of Mercosur trade.
Pesticides banned in Europe, but allowed in South America: Atrazine, Acephate, Mancozeb, Paraquat, and many more.
Diseases they can produce include: Parkinson's, brain damage in children and lower IQ, infertility, genetic mutations.
Nothing in the deal says that EU has to accept anything that does not adhere to EU standards. Any food imports have to follow EU regulations. It only allows (a fairly dismal quota) to go through without tariffs.
So all the bullshit you just said (which I am not even sure I trust) is irrelevant.
This can more some of the incredibly polluting meat (beef) industry to countries where the pollution is lower due to less intensive methods over a larger area, which is a win-win.
This is a boon to any European manufacturer and machining company.
In my opinion it is a net negative for all countries in Europe, but one.
