26 Sep 2018 --- Record high levels of microplastics for the Mediterranean region have been found deep in the sand where sea turtles lay their eggs by University of Exeter researchers. The study identified an average of 5,300 particles of plastic per cubic meter at depths of 60cm on beaches in Cyprus used by green turtles and loggerheads. Researchers say that if conditions worsen such pollution could eventually begin to affect hatching success and even the ratio of male and female turtle hatchlings.
