Because a healthy ocean is essential to the balance of our Planet, it is becoming urgent to find scientific solutions to understand the changes it is facing, and to stop the decline that threatens the largest ecosystem on our planet. 

This is why, in 2021, the United Nations proclaims the decade of the Oceans and invites the global ocean community to develop roadmaps, scientific and technological actions over the next ten years around 10 major challenges.

10 years, 10 challenges to contribute to the Ocean we need for the future we want!

United Nations Decade of Ocean Science for Sustainable Development (2021-2030)

KRESK 4 OCEANS targets the Oceans Decade's Challenge No. 1 to "understand and map land and sea-based sources of pollutants and contaminants and their potential impacts on human health and ocean ecosystems, and develop solutions to eliminate or mitigate them. "

A challenge that KRESK 4 OCEANS wishes to meet by contributing to the development of sustainable, environmentally sound and economically viable solutions

Kresk Takes on Challenge #1: Understanding and Addressing Marine Pollution

 from fishing equipment

other than plastics

other plastics

single-use plastics





Ocean pollution is multiple. It is linked to sewage, sea activities, oil, various chemical products brought by rivers and air, deposits or discharges of dredging sludge and mainly to plastic.

This waste is very diverse in nature and size. The most widespread are single-use plastics (cigarette butts, plastic bags, cotton buds, plastic packaging, plastic granules) followed by waste from fishing equipment.

A marine pollution with multiple facets..

Pollution damages marine habitats.

Waste carries invasive species, allowing them to spread over much longer distances than normal

Plastic disperses toxic materials. As it breaks down, it releases toxic additives in its composition or pollutants that are absorbed from the water.

Animals swallow plastic or micro-plastics, which eventually accumulate in their organs and tissues.

Macro-waste injures or impedes marine animals.

Impacts on the climate, notably linked to CO2 emissions during production, on the economy (only 5% of the value of plastic containers remains in the economy) and especially on marine biodiversity and ultimately on human health.

... and multiple impacts

Our future depends on the health of the ocean.

If we want our actions to be sustainable, it is essential to educate people, and especially future generations, about new consumption patterns.

Even if no more plastic were to end-up in the ocean, the number of microplastics is expected to double by 2050*.

A better understanding of the impact of plastic and its contaminants on marine biodiversity is needed to better protect it in the future.

*WWF 2022

More than 8 million tons of plastic are dumped into the oceans every year, that's 400 kg per second.

Our priority is to stem the flow of plastic to the ocean, by supporting innovative solutions from design to end-of-life.

Raising awareness

Understand the Ocean

Act Onshore

KRESK means "development, growth" in Breton. A name that echoes the challenges of sustainable development. To act concretely, KRESK4OCEANS is committed to 3 development actions for a clean ocean.
