Marine Life and the Environment
The immediate reaction of the diver who finds something interesting is to pick up and take home to better observe and show friends.
This behaviour such as the unnecessary removal of marine organisms should be avoided at all costs because even the mere removal of a stone from its place can affect the life that exists in it or which is hidden under it.

THE PRINCIPLE THAT THE DIVER SHOULD ALWAYS KEEP IN MIND IS THAT HIS PRESENCE WILL ALWAYS HAVE AN IMPACT ON THE ECOSYSTEM OF THE DIVE SITE
