PARIS, Feb 8 (AFP) - Plastic has infiltrated all parts of the ocean and is now found "in the smallest plankton up to the largest whale" wildlife group WWF said on Tuesday (Feb 8), calling for urgent efforts to create an international treaty on plastics.

Tiny fragments of plastic have reached even the most remote and seemingly-pristine regions of the planet: It peppers Arctic sea ice and has been found inside fish in the deepest recesses of the ocean, the Mariana Trench.

There is no international agreement in place to address the problem, although delegates meeting in Nairobi for a United Nations environment meeting this month are expected to launch talks on a worldwide plastics treaty.

WWF sought to bolster the case for action in its latest report, which synthesises more than 2,000 separate scientific studies on the impacts of plastic pollution on the oceans, biodiversity and marine ecosystems.

The report acknowledged that there is currently insufficient evidence to estimate the potential repercussions on humans.

But it found that the fossil-fuel derived substance "has reached every part of the ocean, from the sea surface to the deep ocean floor, from the poles to coastlines of the most remote islands and is detectable in the smallest plankton up to the largest whale".
