Protection of Marine environments have been neglected

Over the years the human activity overexploited all resources knowned on earth untill some rules and sanctions were installed. This prevented most human from abusing of it's ecosystem except in one types of ecosystem. Indeed we have neglected all marine ecocystem because they are almost impossible to control because of it's immense size. It is impossible to make sure that everyone respect all marine environements whether it be fishermen catching endangered species or just boat emptying all their sewage in the sea. Even though the oceans do not take a important part in our everyday life it controls the entire earth ecosytem, one small change in the oceans will have a result of actions that will finally affect us directly.
