Researchers in a new global review investigated the hazards of marine plastic pollution and they warned that all seven species of marine turtles face high risk of losing their population. Researchers found that marine turtles can ingest or become entangled in the discarded debris that currently litters the oceans.

Lead researcher Brendan Godley from University of Exeter in England, said, “When turtles ingest plastic, they can suffer intestinal blockage that can result in malnutrition which can in turn lead to poor health, reduced growth rates, lower reproductive output and even death”.

Godley stressed on the point that every piece of plastic that ever entered a sea still rests there; breaking down and forming a soup of microplastics that could have frightening long-term consequences.

Researchers during the study also revealed some serious knowledge gaps in the diverse and complex pathways in which plastic pollution can harm marine life. Joint-lead author of the study Sarah Nelms, from University of Exeter's Penryn campus said she was in shock after knowing how less is known about the impacts of plastic on marine turtles.

The study recommended that some urgent action is immediately required to better understand the issue and its effects on marine turtles. They also said that some appropriate and effective mitigation policies can be developed.

Entanglement of turtles in plastic debris results in lacerations and increased drag when swimming may result in drowning or death by starvation.
