Beschreibung: With plastics and plasticisers as well as noise pollution in the oceans, we now have relatively new, emerging phenomena that defy the regulatory definitions of pollution. Accurate definitions are lacking also because modern waste, like plastic pollution, is fundamentally different from its predecessors. The sciences involved in tracking, analysing, and understanding the ecological crisis of marine ecologies face severe epistemological problems, because the methods used hitherto are failing: The emerging phenomena are both novel and occurring on an unprecedented global scale. The entire extent to which plastics and plasticisers are floating in the oceans and seas is not visible to the naked eye because a great deal floats below the surface in the form of microparticles. Plastics are not biodegradable, but they are gradually broken down into smaller and smaller particles in the ocean through wave action and intense irradiation from sunlight. Marine organisms confuse these microplastics with plankton; this means that plastics (and the toxins they contain) are increasingly entering the food chain, irretrievably and irreversibly. Around 70 % of plastic waste deposited in the oceans sinks to the sea floor, but in 1997 scientists observed for the first time that an enormous amount of tiny plastic particles were collecting on the surface of the water in the vortexes of ocean currents, also known as gyres. The discovery of the so-called Great Pacific Garbage Patch made it clear that millions of tons of plastic garbage are drifting in the oceans. Since the discovery of high concentrations of microplastics in other gyres as well, it can no longer be denied that a new ecosystem has emerged in which artificial and natural aspects are inseparably connected.
