Know that pigs are one of the most intelligent animals on Earth, smarter than dogs. Some people keep pigs as pets.
Now that you know this, watch this video of a highly industrial pork processing plant where hundreds of pigs a day quickly and systematically go from being brought in by trucks, gassed, and cut and pulled apart many times all the way down to packaged pork chops, and take it to heart. You should never want to eat pork again.
