Since the beginning of time human beings have utilised the 71 % of the Earth's watery surface to dump their rubbish. What has changed, is the massive population and the nature of the artificial anti-products that are now disposed in the world oceans by individuals and industry. Apart from the cost-effective discarding of 'millions of tonnes of sewage and toxic waste' gigantic amounts of plastic is added. ”80% of marine debris originates from land based sources.” Just the plastic alone floats for hundereds of years on the surface and is distributed/ 'flushed' with the ocean currents to all corners of the globe (map). With time the pellets of domestic and industrial waste develop into ever smaller particles. They are given the cute term: 'Tears of the Mermaid'. These toxic, microscopic particles then enter living organisms in the ocean at all levels. They remain and accumulate in the aquatic and terrestial living beings.The degradation of the entire food-chain is the inheritance left behind.
The issue is unfortuntely not sufficiently important to act on, there have been various reports over the years – all in wane. Some attention is generated now as there is a financial impact on large boats having trouble getting thorough the plastic debris.
