Where do critical metals that we use every day for our technologically advanced society come from? We will discuss questions surrounding the exploration and ownership of metallic resources and their exploitation. We benefit, but at what cost to others? To address these questions, we look at individual critical metals and their exploitation in a variety of countries from Africa, to South America, and Southeast Asia including Australia. As an example, cobalt is currently crucial for electric car batteries: see the book by Siddharth Kara (2022) "Cobalt Red: How the Blood of the Congo Powers Our Lives". Should we alternatively get cobalt by the proposed mining of the deep ocean floor? Who has the right to do that? Weekly readings and discussions, and guest speakers lead to mini-research projects on such topics.
