There are at least 6 macro sources of pollution, together with a multitude of concomitant causes, all of which are human responsibility. These contribute to the degradation of the ocean masses and all that lives within it. Let us start with industrial waste, 70% of which ends up in the sea: we are talking about sewage containing all kinds of chemical poisons and solid waste. This is followed by oils and their derivatives: according to a 1995 Nasa study, over 2 billion litres end up in the sea every year⁴. Plastics and microplastics also have impressive numbers: 86 million tonnes of plastic currently drift into the unknown⁵. Waste water is another important pollution factor: only a small percentage of countries treat waste water before releasing it. Instead, agricultural activity releases pesticides and fertilisers whose chemical elements have given rise to Dead Zones. Read carefully for a moment: ‘giving birth’ to ‘dead zones’. It sounds like a paradox, but it really isn't. These are places where no living thing is able to live any longer. The most famous Dead Zone is located in the Gulf of Mexico and is as large as New Jersey. Finally, let us not forget the phenomenon of Eutrophication, or even radioactivity, thousands have been nuclear tests carried out by governments in the past years to test weapons of mass destruction. Nuclear power plants release radioactive water into the oceans and, in this regard, one of the latest fresh news in 2023 is the spillage of radioactive water accumulated after the Fukushima⁶ disaster.
