National Pig Day 2011: Celebrate March 1 (PHOTOS)

Today is the time to give thanks to our porcine friends. Started by sisters Ellen Stanley and Mary Lynne Rave in 1972, National Pig Day is "to accord the pig its rightful, though generally unrecognized, place as one of man's most intellectual and domesticated animals," according to Rave.

Instead of chowing down on some pork, we here at HuffPost Green recommend celebrating National Pig Day by...well...not eating them! Instead, you could help support an organization that cares for abandoned pigs, like Pigs Animal Sanctuary or Pig Pals Sanctuary, or a pig adoption organization like Pig Placement Network. You could even send an adorable e-card to your friends to spread the piggy love. If you do find yourself extremely hungry on this National Pig Day though, you could always ditch the bacon and grab some free pancakes since today is also IHOP's National Pancake Day.

Check out these adorable photos of pigs, and vote for your favorite!
