Here are two videos about it:
- One from Mercy for Animals, narrated by Alicia Silverstone. Disturbing images.
One from the U.S. Poultry & Egg Association. You don’t need to watch the whole thing (it would be a waste of time).
I found the first video in this nice article by Nicholas Kristof about “what our great-grandchildren will find bewilderingly immoral about our own times — and about us.”
YouTube suggested me the second one.
P.S. I was going to stop writing in English (it is hard enough to write in Portuguese), but then I saw that more than 20 per cent of my visitors are from the United States. Now I don’t know what to do.
