Take only pictures and leave only bubbles and I believe in that, but how I do it is my responsibility and even in no glove places I carry a pair for emergencies!

You are right about the fins! In addition not just fins but awareness of your body underwater! A fin gently at rest does no harm, but one snapped because of being unaware is what damages all manner of reef life! We are a part of the environment but because we are given responsibility for our world we are held to a higher standard that a storm or parrot fish! But that is the life cycle of a healthy reef!
