PLASTICS, PLASTICS EVERYWHERE
Professor Peter Ryan, Vonica Perold, Eleanor Weideman, FitzPatrick Institute of African Ornithology, Department of Biological Sciences, UCT and Aaniyah Omardien, founder and director of The Beach Co-op NPO
The problem of waste plastics, especially in marine ecosystems, has become a high-profile environmental issue, but it extends much more broadly, especially as most marine plastics come from land-based sources. This course will discuss the evidence for impacts of plastics on marine and freshwater ecosystems globally, and more specifically in the southern African region. It will also report the distribution and abundance of plastics in marine and freshwater ecosystems in South Africa and adjacent oceans, based on sampling at sea, in rivers and on land. The extent of the problem will be compared with other regions of the world. The course will conclude with an exploration of the various options being pursued to tackle the waste plastics problem in South Africa.
