Alexander Gerst begibt sich für die Fernsehserie “Mission Erde” an Orte, bei denen mittels Forschung versucht wird, das fragile Ökosystem Erde besser zu verstehen. Auf seiner Expeditionsreise traf er auch die Wissenschaftlerin und Leiterin des...
Within this precarious time concerning world wide pollution, it is still surprising how far the dimension of plastic pollution actually is. Apparently no place is safe from the little small non degradable particles. Even within the Mariana Trench, that marks with a depth of almost 11 km the deepest point on earth, plastic was found.
It is known knowledge that most of the plastic that pollutes our ocean, actually around 94%, is found on the seafloor. But still the new information reveals the shockingly high contamination of plastic within the most remote place, the deep sea. The photograph shows plankton, sampled within the Mariana trench, that ingested a blue plastic fiber.

“Manmade plastics have contaminated the most remote and deepest places on the planet,” said the Chinese researchers. “The hadal zone is likely one of the largest sinks for microplastic debris on Earth, with unknown but potentially damaging impacts on this fragile ecosystem.”
Other recent studies have demonstrated the reach of human impacts into the Mariana Trench, with “extraordinary” levels of pollutants being found there and plastic being found in stomachs of deep sea creatures. Microplastics have also been found in Swiss mountains, tap water and human faeces.
Microplastics have been shown to harm sealife, which is already being damaged by overfishing and climate change. The researchers said: “Further work to evaluate the impacts of microplastics on fragile hadal ecosystems is urgently needed.”
