By screwing the fins to your surfboard, you prevent them from becoming harmful waste for the oceanic fauna reaching the bottom of the ocean, becoming "micro-particles" as food for the fish, those same fish that in the future you will be able to put in your mouth...
With just a small gesture by screwing your fins, you can do more than you can imagine !
