Vol. 37 No. 2 (2020): The Perennial Quest
The Perennial Quest

With the subtitle, "Discovering our place in the world," this issue offers insight into how we exist and subsist in, adapt to, and sometimes harm our planet—from the retrofitting of buildings to improve their resilience and the design of housing to minimize the effects of harsh urban conditions, to the development of alternative fuels, and ultimately to the mining and subsequent abandonment of natural landscapes.
