Working together
towards
zero marine litter!

MerTerre is doing everything in its power to reduce the waste that ends up in the sea.

80^%

waste at sea
come from the earth

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.

Characterize

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

Raise awareness

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

Coordinate

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

Support

MerTerre supports stakeholders through data analysis for the co-construction of plans for the prevention and management of diffuse litter.

They support our mission

Public partners, companies, foundations: they support us and reinforce the impact of our missions.

Why should you make a donation ?

Almost all of your donations allow us to continue our coordinated actions to protect our planet.

All donations are tax-deductible

A donation of 50€ costs you 17€ and enables MerTerre to help an association to characterize waste.

A donation of 100€ costs you 34€ and enables MerTerre to organize a large-scale clean-up.
