Joelsnan says "Who brought the plastics plight to world attention? A Brit, David Attenborough and his Britis team."
I am sure publicity from David Attenburgh has helped but in fact the problem of plastics especially in our seas was first addressed by Dutchman Boyan Slat. In 2011, at age 16, Slat came across more plastic than fish while diving in Greece. He decided to devote a high school project for deeper investigation into ocean plastic pollution and why it was considered impossible to clean up. He later came up with the idea to build a passive system, using the circulating ocean currents to his advantage, which he presented at a TEDx talk in Delft in 2012. He then went on to found Ocean Cleanup, of which he is CEO.
The Ocean Cleanup is non-government engineering environmental organization based in Netherlands, that develops technology to extract plastic pollution from the oceans. After a couple of years of various system tests, its real-world collection system failed after two months and was towed to Hawaii for inspection and repair, with plans to return in summer 2019.
The organization conducts scientific research into oceanic plastic pollution. It was founded in 2013 by Boyan Slat, a Dutch-born inventor-entrepreneur of Croatian origin who serves as its CEO. It has conducted two expeditions to the North Pacific Gyre, and publicized scientific papers. The clean-up approach uses barriers in ocean gyres to scoop up marine debris as the barrier is pushed by wind and current. The project aims to launch a total of 60 such systems in the patch by 2021. They predict this capability could clean up 50% of the debris in the Great Pacific Garbage Patch in five years.
