A scuba diver notices something strange about a huge shark. Within seconds ... he will save its life!

Marine pollution or the pollution of the oceans and seas is not only harmful to marine life in the form of poisonous substances, but also through physical injury and mutilation.

We all know, in fact, that many turtles die of suffocation because they mistake plastic bags for jellyfish and try to eat them! Or, as in this case, that there is an uncountable number of marine animals that remain entangled in commercial fishing ropes or nets which end up killing them. Fortunately, sometimes being in the right place at the right time -- and with just a small knife, a life can be saved! Kudos to this scuba diver!
