Speaker PROFESSOR RICHARD THOMPSON
Plastics in the Sea. Professor Richard Thompson OBE - International Expert from the University of Plymouth
Professor Richard Thompson OBE featured in a three-part BBC Radio 4 series about our love/hate relationship with plastic. Plastic Fantastic examined how the materials have become part of our everyday lives but also how they have become a global problem. Professor Thompson - one of the foremost international experts on the issue of marine plastic pollution - featured in all three episodes, which also explored efforts to find a global solution to the issue of plastic waste.
A worldwide problem
Marine litter is a global environmental problem with items of debris now contaminating habitats from the poles to the equator, from the sea surface to the deep sea. This litter has negative consequences for wildlife, for economies and on human health. Over 700 species, including commercially important fish and shellfish, are known to encounter marine litter in the environment. The vast majority of the litter found on shorelines, at the sea surface and that affecting marine life is plastic, and it has been estimated that up to 12 million tons of plastic litter could be entering the ocean every year. There are solutions, but there is an urgent need for action.
At the forefront of marine research
The International Marine Litter Research Unit is proud to stand at the forefront of research in this area. In 2004 our team was the first to reveal the widespread occurrence of microscopic particles of plastic debris at the sea surface and on shorelines – pieces which we described as microplastics. We have published numerous scientific papers and reports on this topic, have advised governments and international organisations worldwide and we continue to research not only the extent of the problem, but also the solutions.
The International Marine Litter Research Unit has a mission – to further our understanding of the impacts of litter on the environment and society, and to identify the solutions and the pathways necessary to achieve them.
In 2004, Professor Richard Thompson OBE and his team showed that microplastic particles have accumulated in oceans since the 1960s and are now present worldwide. The International Marine Litter Research Unit described the accumulation of fragments of plastic debris in the oceans and much of its focus is on these microplastics.
Our work has shown that microplastic debris now contaminates shorelines worldwide; that they are present in substantial quantities in remote locations such as the deep and the Arctic. A range of marine organisms including commercially important species can ingest these pieces and laboratory studies have shown there is potential for this to lead to harmful effects.
Former US President, Barack Obama, signed a bill outlawing the sale and distribution of toothpaste and exfoliating or cleansing products containing microbeads which are a type of microplastic. Our work on this topic has helped inform governments around the world. We submitted evidence to the UK Houses of Parliament in relation to the Environmental Audit Committee enquiry on microplastics.
Our findings are underpinned by research conducted by the team at the University of Plymouth and in collaboration with other leading scientists worldwide. This expertise has guided industry, informed educational and artistic initiatives that raise awareness, and has provided evidence for government agencies and international organisations such as the United Nations.
