Pollution de la mer

Million tonnes of plastic litter pollutes the ocean every year

Marine litter has long been a problem and threat to marine life: marine mammals, seabirds and fish die each year from being entangled in or ingesting marine litter.

Every year 6.4 million tonnes of plastic, with all the toxins they contain, pose a threat to sea life and ecosystems. Plastic is usually made of cellulose, carbon, petroleum, or natural gas. It consists of long chains made up of many repeating molecular units. For the natural environment, plastic is a foreign body and does not biodegrade. Pieces smaller than 5 mm in size are called microplastic. Sources for microplastics in the ocean include cosmetic products, textiles such as fleece jackets, rubbish washed from land and ships that dump their plastic waste in the ocean (even though it is prohibited). The fishing industry accounts for 10% of marine debris. Nets and fishing gear get lost or are thrown away into the ocean. These "ghost nets" continue trapping fish for many decades. Plastic can transport plant and animal species across great distances to other regions. These passengers unsettle the balance of the sensitive ecosystems of their destinations. Plastic can also cover coral, marine sponges and mussel beds, preventing species from populating them and cutting marine organisms off from the exchange of oxygen.
