Oceans play a fundamental role in sustaining life on our planet. Apart from being central in regulating Earth’s climate, oceans provide food and other goods to humans and animals, as well as shipping routes for transport of goods and people. A major problem is related to the rapidly increasing amount of waste found in our oceans, referred to as ‘marine litter’.
