This is part 2 of the broad discussion that André, Bob, Erin, and Simon went into, which began with the sustainable development goals (SDGs) and why it seems so challenging for the world to achieve the goals. Part 2 of the discussion started with Erin’s question on whether the issue with the capitalist system is that negative environmental externalities are not sufficiently factored into economic decisions. We touched on ethical issues such as the Trolley Problem, why or why not poverty alleviation is the most important SDG, the idea of the ecological footprint and what we don’t know about SDG 12 on sustainable consumption and production, and the true value of the SDGs for countries. As always, we do not profess to have all the right answers to these questions but enter into these exchanges to learn new perspectives on the difficult and challenging questions about sustainability. We hope you do too!
