I saw this a few years ago.. it turned my stomach, but I'm glad I saw it. Maybe I should watch it again. The disconnect between things we buy/do and what goes into them can be so huge, and it's so easy to get lulled back to sleep.

I have no idea what this is doing on HN, but if you can stand it, do watch it. You might be sad/angry after you did, or have nightmares, or become veg(etari)an. It is not pleasant and will not leave you cold. If you already are depressed because of the season or something, bookmark it for later maybe.
