We recently told you about South Korean officials who buried more than 1 million pigs alive in an ill-conceived effort to control foot-and-mouth disease. PETA has recently obtained video footage of the killings, which shows workers as they toss live pigs on top of one another in a mass grave. Pigs are pushed out of trucks and into trenches, covered with dirt, and left to suffocate. Air pockets form in the soil, allowing some pigs to breathe, meaning that some may languish for days, injured and surrounded by dead pigs, before they die.
