Oceanic microplastics: the implications of tiny pollution
My classmate Dom Lawler deserves most of the credit for producing this video on microplastics, made in less than four days using iMovie for a university assignment on aquatic pollution.
Check the film out and watch some other related one on YouTube if it sparks your interest.
Here’s some quick details on the plastic pollution issue:
– 10% of the 280 million tonnes of plastic produced annually worldwide ends up in the ocean, contributing to 60−80% of all marine debris (Kaposi et al. 2014)
– First reports of plastic litter in the ocean were in the 1970s (Andrady 2011)
– Plastics could take centuries to completely mineralise or biodegrade (Moore 2008)
– 10% of all static fishing gear – including plastic nets, fishing line and ropes – is lost worldwide (FAO 1991)
– In the environmental context, microplastics are regarded as pieces of plastic debris less than 5mm in size
– Studies have found that 267 species of marine organisms worldwide are known to have been affected by plastic debris, a number that will increase as smaller organisms are assessed. (Moore 2008)
