3.2 Tragedy of the Commons - Biodiversity
In this activity, we will explore two examples that some people attribute to the tragedy of the commons. The first is the collapse of the cod fisheries off Newfoundland, and the second is the accumulation of plastic in our ecosystems, particularly the ocean gyres.
I anticipate that teachers will need to circulate while the pairs are trying to explain what they are reading. I would advise pre-reading the systems maps so that you know what the symbols mean.
Study the Collapse of Newfoundland cod fisheries, Northwest Atlantic, outlined in the Regime Shift Database. Work in pairs to collaboratively explain the information contained on the page. Ensure you look at the system map illustrating the feedback loops in the system.
Read this summary of the outcome of the latest round of negotiations for a global treaty on plastics.
Produce a stakeholder map that shows:
- the need for a global treaty
- the stakeholders that are advocating for the treaty
- the stakeholders that are blocking the progress to a treaty
Summarise why plastic pollution is an example of the tragedy of the commons and why you could argue it is not an example.
