Nature just
can't digest THEM

Marine animals such as mammals, birds, sea turtles, fish and invertebrates are known to ingest waste, especially plastic waste, because they confuse it with their usual food.

Through our actions,
we protect ecosystems
and their biodiversity.

MerTerre is a key and influential actor on the litter problem.


MerTerre develops methods to characterize diffuse litter in all types of environment.

MerTerre develops educational and awareness-raising tools to change behavior.


Thanks to the collaborative science platforms it coordinates, MerTerre strengthens local stakeholders and their actions.
