In terms of the list of reasons to go veggie, or just eat less meat, animal welfare ranks below environmental concerns, but is still important to me.
If you didn't know, PETA are utter scum. Animal rights activists on the whole are delusional and tend to value animal life above human life to the extent they're willing to kill humans to get their message across: they are basically terrorists.
PETA kill >95% of their animals within one year.
Last week, in Sydney, they mock barbecued a dog (looking just like the breed of my dog, an irish terrier) outside a mall.
