NEW YORK (AP) — There's extensive evidence that pigs are as smart and sociable as dogs. Yet one species is afforded affection and respect; the other faces mass slaughter en route to becoming bacon, ham and pork chops. Seeking to capitalize on that discrepancy, animal-welfare advocates are launching a campaign called The Someone Project that aims to highlight research depicting pigs, chickens, cows and other farm animals as more intelligent and emotionally complex than commonly believed.
