Plastics are entering our food chain. The time has come for “us” to decide. Do we bury our heads in the sand, which incidentally is now made up of microplastics too, or do we take action.
Young fish prefer to eat plastics!
The evidence is here! Sweden’s Uppsala University researchers have discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.
“Fish reared in different concentrations of microplastic particles have reduced hatching rates and display abnormal behaviour. The microplastic particle levels tested in the current study are similar to what is found in many coastal habitats in Sweden and elsewhere in the world today,” says marine biologist, Oona Lönnstedt, lead author of the article published in the scientific journal Science.
This is the first time an animal has been found to preferentially feed on plastic particles and is cause for concern’, says Professor Peter Eklöv, co-author of the study.
Another study, found smaller filter-feeders often cannot tell the difference between micro-plastic and plankton given the plastic concentrations in the water.
The chair of the Commons Environmental Audit Committee, in the UK said the evidence of plastic pollution in the Thames was deeply worrying. “Pieces of plastic carried downstream will be eaten by oysters in the Thames estuary. If you eat six oysters, you’ve probably consumed 50 particles of microplastics, which have been washed down the sinks of homes in London and carried downstream.”
