These patches of terrestrial debris have unsuspected ecological consequences.
Confused with plankton, this decomposing rubbish is ingested by mammals, turtles and birds and obstructs their digestive system.
Moreover, in the North Pacific, this mass of garbage provides a breeding ground for a species of water spider, Halobate sericeus. It now threatens to unbalance the entire ecosystem.
The Mediterranean, for its part, has on average the highest densities of plastics in the world, with 250 billion microplastics.
In this semi-enclosed sea, the water renewal rate is 90 years, while the persistence of plastics is much higher.

“How can we prevent packaging from washing up in the oceans as well?” asks Gérald Martines. “This material is neither bad nor good. It’s only a problem when it becomes waste, and that’s what the industry has to respond to.”
