I have to agree with this no the topic of mass industrial farming... which has chosen a balance towards volume and profit over other aspects. From the purely economic point of view, it makes sense... after all, a company doesn't have to price in externalizes that their don't directly bear costs for... so if there is antibiotic resistance being bred.... well, it doesn't affect their bottom line... until later. Of course, just because it makes sense doesn't mean that it is right... for me, I would argue that the true cost of the practices aren't being factored into the final price of the product.... and this is where we are for most of the pollution debate. How to price this sort of thing... for decades, we've said that pollution is essentially free... and now we know that the costs of this are not exactly free... they are just borne by someone else!
I'm not 100% sure if this protest is specifically corporate or not... it seems to be a broad swathe of the farming sector... so it is likely to be a mix.
