Was St. Francis of Assisi the first eco-warrior?

Yes He was the first Eco-warrior as he fought to save the planet. he is now the Patron Saint of animals and Ecology.

.

Heavens no, he lived 700 years before anyone even thought of being an activist for the environment. St. Francis of Assisi was an activist for his Lord and Savior, Jesus Christ, if some of his actions looked like the current activities of an eco-warrior that is nothing more than modern romanticizing and trying to use current language that would make no sense back in his day and age. St. Francis was above all a Catholic Mystic, which is someone so deep into prayer that they look a little mad to the world around them, but that comes from holiness which the world is incapable of understanding.
