The oceans are full of plastic.
Le plastique est une contaminante engendre et présente un danger pour la biodiversite marine.
L’utilisation a grande échelle de produits chimiques, ainsi que des déchets industriels, contribue beaucoup au production du plastique dans les oceans aujourd’hui.
Selon la WWF, la pollution marine en microplastiques finit chaque annee avec entre 19 a 23 millions de tonnes de plastiques qui submerge les eaux marins.
L’ocean contiendra jusqu’a 2050 1 tonne du plastique pour 3 tonnes de poissons d’ici (2025). And dès 2050, si rien n’est fait a reverser le rythme, elle pourrait contiuer 2 tonne du plastique pour 5 tonnes de poissons.
The plastic that pollutes the ocean is not just one type of pollution : it is a mixture, a composite, a complex.
This contamination consists of a large range of products, including: plastic bottles, bags, trays, cups, lids, floppy discs, straws, plastic wraps, etc.
These products all have a long shelf life, are often disposed of in non-recyclable ways, and they can accumulate on the ocean’s surface or in gyres.
They are also ingested by aquatic creatures, such as fishes or shellfish, and by animals that live near the coast, such as seabirds and cetaceans.
The marine ecosystem is weakened when these dechets reach the apex of the food chain.
As a result, the species that depend on it suffer a decline in their populations.
Those that depend on fish are particularly affected, as they rely heavily on them to survive and reproduce.
These species are also at risk from plastic debris that is discarded into the sea by humans, such as cigarette butts or empty bottles.
There are many ways to prevent these plastic debris from entering the ocean: reducing the use of single-use plastics, using less packaging when buying goods, disposing of trash in better ways, and recycling.
Some plastics, such as polycarbonate and polypropylene, can be recycled to form new products that are more environmentally friendly.
The problem of plastic debris is complicated, though: some types of plastics can decompose in the ocean and release toxic substances into the water.
For example, plastic bottles and caps are a common source of toxic chemicals that can be released into the water by marine organisms, such as fish.
These chemicals are a major threat to the survival of many marine organisms, such as coral reefs and dolphins.
They are also a significant risk to human health, as they can cause cancer and endocrine disruption.
The best way to avoid these pollutants is to make informed decisions about the products we buy and dispose of, and to encourage companies to choose more sustainable materials if possible.
Investing in alternative solutions for the production of products, such as recycled plastic, is an important step toward a more sustainable future.
In the long run, we can reduce our consumption and recycle more and more plastic, which will help us save our planet.
In the meantime, we need to act against this pollution. The best place to start is at home, by limiting the amount of disposable plastic we use.
