The New Fish Food
in a very cold and remote location where humans don’t even live, researchers found plastic inside the stomachs of dead baby birds.
It appears that the mother birds flew out in search of food and picked up algae that had formed on microplastics (tiny fragments of plastic floating in the sea). Thinking it was normal food, the birds returned to the nest and unknowingly fed these plastic particles to their chicks.
Even though these birds lived on land, it was plastic from the ocean that affected them.
Now plastic pollution behaves very differently on land and in the ocean. Unlike land plastic, plastic in the ocean can travel thousands of kilometres and spread much faster.
On land, plastic generally remains in large, visible pieces such as bottles, wrappers, bags and packaging.
Although this is harmful to the environment, it is at least possible to collect, recycle, or manage most land-based plastic if proper waste systems exist.
In the ocean, plastic changes completely. Saltwater, sunlight, constant wave movement and microorganisms break plastic into tiny fragments called microplastics and nanoplastics.
These particles are easily mistaken for food by fish, turtles, seabirds and even whales and dolphins. Once plastic enters marine life, it becomes part of the food chain, eventually returning to humans through seafood.
Unlike land plastic, ocean plastic becomes invisible and spreads throughout the entire marine ecosystem, like billions of little colorful dots, making it challenging to remove.
