Exploring the Artificial Cryosphere

Exploring the Artificial Cryosphere

Nicola Twilley

September 18, 02018

The invisible backbone of our food system is a man-made, distributed, and perpetual winter of refrigeration we've built for our food to live in. It has remade our entire relationship with food, for better and in some ways for worse. The time has come for us all to explore the mysteries of the artificial cryosphere.
