How many lives have been lost to microplastics on the dinner table

- Nov 22, 2019-

It is well known that many Marine fish larvae feed mainly on plankton and plants in coastal areas, but unfortunately, plastic has recently become a common item on the menu of this sumptuous buffet.1. The JPGMicroplastics are increasingly becoming part of the ocean's habitat.An international team of researchers led by researchers at the Pacific island fisheries science center in Honolulu says Marine fish are in their infancy.In particular, the scientists studied areas near the surface of the Hawaiian coast that are rich in plankton.They found that there were a disproportionate number of fish larvae around, but they had to share the ocean with a large number of plastic particles that were far from what they were supposed to eat.The researchers also found plastic in the digestive tracts of dissected fish larvae, which is used more than twice as often as in adjacent waters.2. JPGAlthough, there is no mature study on how microplastics affect the bodies of young fish.What is certain, however, is that these young fish can apparently cause indigestion, malnutrition and other serious problems by eating plastic with adult fish.About 8 percent of all examined fish larvae absorbed the small plastic particles, the researchers report in the journal PNAS.3. The JPGThe scientists also found that if it weren't for the microplastics, the fish wouldn't have a better nursery: near the coast, underwater waves wash algae and plankton into thin films.The "oil slick" is similar to an oil film and covers nearly eight percent of Hawaii's coastal waters.Although these areas are limited in scope, more than 40 percent of fish larvae live near them.In addition, the scientists observed coral reefs that gave birth to the first species in Hawaii's waters, as well as more pristine habitats in the open ocean and other Marine environments.The fish that grew up in these waters were not only larger, better developed, but also more athletic than their peers in other waters.4. JPGTo get as complete a picture of these waters as possible, they studied more than 1,000 square kilometers off the coast of Hawaii.In satellite images, the reflection of sunlight shows the reflection of sunlight in a specific area, so a relatively accurate location can be determined.The field researchers then used plankton nets to collect samples about a meter deep, and then sequenced and analyzed everything they pulled out of the water under a microscope.5. JPGThe researchers' findings show that microplastic material collected off the coast of Hawaii has an average concentration at least eight times higher than that of the infamous great Pacific dump.The researchers also point to a more profound danger: if Hawaiian plankton larvae survive, they could one day grow into fish stocks.Swordfish and tuna are among the fish that eat microplastic particles and are a big source of another microplastic in the human food chain.So the microplastics eventually make their way through the food chain to the human table.
