A recent Reefbase scientific study contains a line that may be all the reason we need to save the seas:
"Coastal environments can cleanse the soul, stimulate the mind, and restore the body."
Refreshing to see a philosophical, emotional statement in a scientific paper.
This is not to say it has been scientifically proven that coastal environments do this. But then again, isn't it obvious? It's why so many people love the ocean.
