March 17 has always been green, in honor of… well, ostensibly in honor of St. Patrick, though history gives no indication of that being his favorite color.

But consider: Didn’t St. Patrick travel around Ireland on foot, encouraging Irish farmers to plant potatoes? Maybe he really was a “green” saint, connected to the earth and concerned with sustainability.

And don’t the Irish traditionally like to throw back a pint, especially on March 17? I just Googled “organic beer” and got 106,000 results. I think it’s safe to say St. Patrick would approve.
