Oceans, plastic mystery
Of all the plastic waste dumped into the sea, scientists found that in 1%. Where did the remaining immensity? Survey become an invisible toxic pollution.
Would the plastic changing marine ecosystem without anyone able yet all the consequences? Now part of the oceans, as well as algae or plankton, waste plastics are everywhere, from the Arctic to Antarctica through the tropical seas. Several studies agree to say that nearly 50 billion pieces of plastic polluting the oceans. But here's the mystery: the vast majority (! 99%) of this waste has gone. Where did it go? Is ingested by marine organisms? Scientists around the world - oceanographers, environmentalists, microbiologists ... - now investigating this plastic became invisible.
A hunt
Until now, the scientific community knew that this waste fractionnaient in microplastic, particularly under the action of the waves and sun. It concluded that the plastic pieces remained mostly clustered on the surface. But recent studies have invalidated this hypothesis. Since these particles, which represent almost all plastic waste from the ocean, focus the attention of researchers: they are the heart of the problem because their ability to enter the environment seems endless. Seabed, ice, coast, wildlife ...: This documentary explores, in many scientific company, all tracks to understand where the plastic cover is, and wonders about the impact of this massive pollution.
