Not claiming to be be an expert by any means, but my first 14 years of life were spent growing up on a farm, and I started learning about farming as soon as I could walk.
My opinion on any issue that involves mostly recent (past 40 years) poor practices in farming that present negative effects to our environment, health and well-being, I have to put the blame on corporate farming, 100%.
They overdo everything; fertilization, round-up and other glyphosate based weed control agents, antibiotics... you name it and they overdo it, because more is always better in their minds, which operate solely on simply doing any and everything, no matter how harmful, to increase their profits.
I'd likely be supporting the farmers if they aren't corporate.
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.
