In the face of climate change, deforestation and biodiversity loss,
creating a sustainable version of civilization is one of humanitys
most urgent tasks. But when confronting this immense challenge, we
rarely ask what may be the most pressing question of all: How do we
know if sustainability is even possible? Astronomers have inventoried
a sizable share of the universes stars, galaxies, comets, and black
holes. But are planets with sustainable civilizations also something
the universe contains? Or does every civilization that may have arisen
in the cosmos last only a few centuries before it falls to the climate
change it triggers?
