The wide scale of marine pollution from nutrient pollutants and plastics in the oceans has too many consequences, from falling marine biodiversity to the impact of pollutants entering the food chain. Currently overfishing, direct discharge of human waste, pollutant land runoff, direct pollution from shipping and mining industries, and millions of tonnes of non-biodegradable human waste are having a massively detrimental effect on marine life around the world. Biodiversity experts have calculated that we are currently loosing 200-2000 species a year, many of these from the world’s oceans. Many land dwelling species and many people rely on fish for survival, not to mention the potential health risk from the rising toxin levels present in both farmed and wild fish. Scientists are theorising many ways to reverse climate change, forests can be replanted, oil spills can be cleaned up, but species cannot be “de-extinct”.
