MMA fighter Justin Wren left the octagon and for the past 5 years has been fighting slavery and oppression in Africa. Wren has helped dig wells for clean water, grow & harvest food, and buy back land that was taken from the Pygmy people. He’s also working to replant trees in the areas deforested by companies seeking to exploit minerals there. He stopped fighting people to start fighting for the people. A true hero, indeed.
