Panaji, September 20
Global plastic manufacturing has gone up from 300 million metric tonnes to 360 million metric tonnes within the final 5 years, claims a scientist from the Goa-based National Institute of Oceanography.
Also, microplastics pose a critical menace to the setting as they get into the our bodies of marine animals like fish, turtles, shrimps, seabirds, after which enter the meals chain, affecting people as properly, scientist Mahua Saha stated.
She was addressing a webinar organised by a Mumbai- based mostly NGO in collaboration with the National Centre for Coastal Research on Thursday, forward of the International Coastal Cleanup Day which was noticed on Saturday.
Plastics lower than 5 millimetres in size are known as ‘microplastics’ and the comparatively bigger particles, of greater than 5 mm, are labeled as ‘macroplastics’.
Speaking on Microplastics: An rising menace to marine setting and biodiversity, Saha stated, “Plastic production has been constantly increasing. In just five years, the global plastic production increased from 300 million metric tonnes to 360 million metric tonnes.” Out of this, 50 per cent is single use plastic and solely 9 per cent is reusable, the place is the remaining going? Is it accumulating on the shoreline and coast column? She stated.
“Plastic contaminant study needs to be expanded more towards open oceans. If there is so much amount of plastic pollution on the coasts, then imagine how much is there in the open oceans,” Saha stated.
It will not be solely necessary to make the coasts plastic- free, however it’s also advisable to test that plastics don’t attain to the ocean beds, she stated.
Saha stated extra research should be undertaken on the impression of plastic on the setting.
“Also, to understand marine pollution it is important to study the terrestrial aquatic systems like rivers and other water bodies,” she added.
The National Institute of Oceanography is among the constituent laboratories of the Council of Scientific and Industrial Research (CSIR). PTI
