St. Dominic - Carbon footprint
Like many saints, St. Dominic did a lot of traveling in his lifetime. However, between 1218-1219, the founder of the Dominican Order notched up an impressive 3,380 miles on foot during his preaching tour of France, Italy, and Spain. He would no doubt be championing a greener way of getting around!
