Exploring Environmental History

This edition of the podcast explores the story of the ozone hole during the 1970s and 80s and what lessons can be learned from this environmental problem for dealing with global warming. It suggests that not applying the cautionary principle to the ozone thinning in the 1970s led to the emergence of the so called hole in the ozone layer. In the second half of the podcast Liza Piper explores the question how the arctic environment shaped Northern Canadian society during the last stages of the Little Ice age and why this is relevant for the present.
