Plastic production is increasing. Going by business-as-usual, the production of plastics is projected to increase annually by roughly 3.8%, with a large portion of that growth in Africa and the Middle East.
Plastic production contributes significantly to climate change. Over 99% of plastic is derived from fossil fuels. Emissions from plastic emerge not only from the production and manufacture of plastic itself, but from every stage in the plastic lifecycle.
Globally, 6% of all plastics ever produced are recycled. A mere 1% is recycled more than once.
REFUSE. REUSE. REPAIR. REDUCE. REGENERATE. RECYCLE.
The impact of the global chain of plastic products disproportionately impacts persons, groups, and peoples in vulnerable situations and those located in the vicinity of large-scale industrial complexes.
“Women in particular bear the brunt of plastic-related toxicity risk due to higher aggregate exposure to plastics in the household and even in feminine care products.” – United Nations
Most plastic on the South African coast comes from local land-based sources, centred around urban areas. Regular surveys of debris on sandy beaches around the South African coast since 1980’s show that densities of plastic items are consistently greater close to urban centres than at remote beaches. Typically 2-3 orders of magnitude greater.
RIVERS AND STORMWATER CANALS TRANSPORT LITTER OF URBAN ORIGIN TO THE COAST
Stormwater outlets are a significant source of litter to beaches.
(Weideman, Perold, Arnold et al., 2020)
UP TO 57% OF PLASTIC DEBRIS IS ASSOCIATED WITH ON-THE-GO FOOD PACKAGING
Banning unnecessary food packaging such as individual sweet wrappers could result in a significant decrease in litter loads.
(Chitaka and von Blottnitz, 2019)
HISTORY AND CONTEXT MATTER
There are clear socio-economic differences in how much and what type of plastic is generated, and where it ends up.
(Marais, Armitage, and Wise 2004; Armitage 2007)
LITTER TRAPPED IN A ROCKY INTERTIDAL ZONE DIFFERS TO THAT ON A SANDY BEACH
We see differential retention of litter washing ashore due to the physical structure of the shoreline, combined with sand inundation and biotic interactions with litter items.
(Weideman, Perold, Omardien et al., 2020)
Activities carried out by The Beach Co-op have contributed to several scientific publications thus far:
- Ingestion of plastic litter by the sandy anemone Bunodactis reynaudi (Weideman et al. 2020) (see blog).
- Quantifying temporal trends in anthropogenic litter in a rocky intertidal habitat. (Weideman et al. 2020)
- A synthesis three decades of socio-ecological change in False Bay, South Africa: setting the scene for multidisciplinary research and management (Pfaff et al., 2019)
