Save the Sharks in the Oceans
Not so rarely if you jump in the water all what you can see is: no fish, bare rock and lots of sea urchins feeding on the algae. If you ever try to snorkel or dive in Mediterranean sea you surly know what I am talking about. This was what I saw when I jumped in to the water of the cost of Croatia for the first time. And I thought how beautiful it was. Simply I did not know any better back then. Same like many other people as these days it is not so easy to start your underwater experience on pristine coral reefs. More likely you are going to see death coral, jellyfish, algae overgrowing the corals, lots of bacteria and most of the large animals long gone.
