The plastic legacy at the bottom of the planet

At the bottom of the world, where few humans have ever set foot, an unwelcome visitor has arrived. Antarctica – the vast, frozen wilderness of ice and snow – is …
BAS researchers play leading roles within the Scientific Committee on Antarctic Research (SCAR) as chair and members of the Plastic Action Group, a group which aims to assess the current state of the problem, share knowledge and expertise and propose solutions to the problems of plastic pollution in Polar ecosystems.
Research by BAS scientists on Bird Island has influenced fisheries policy in the region to reduce seabird and marine mammal entanglements and deaths. These have reduced significantly since the introduction of legislation in the late 1980s prohibiting the disposal of plastics overboard and with improvements to the safe disposal of packaging bands. BAS has also studied the marine debris on the beaches near its stations for over 30 years and reports to the Commission for the Conservation of Antarctic Marine Living Resources on an annual basis.
Based on BAS led research, a UK policy paper on reducing plastic pollution in the Antarctic and Southern Ocean was presented to the The Committee for Environmental Protection (CEP) at the Antarctic Treaty Consultative Meeting (ATCM) 2019. The resulting Resolution contained several recommendations to minimise plastic pollution in Antarctica and was endorsed by the ACTM. Several CEP members have since initiated practical steps to minimise microplastic pollution from their ships and research stations.
The treaty Consultative Parties recommend that their Governments (Resolution 5, 2019):
