Sam Lin-Sommer in Atlas Obscura:
THE SUN IS BARELY VISIBLE in the soot-filled sky; for thousands of miles in every direction, the air is gray and unseasonably cold. Crops are dying en masse, and an age-old question arises: “What will we eat?” If humans are faced with a volcanic winter (an eruption-induced catastrophe that scientists say has a one in six chance of occurring in the next century) or a nuclear winter (its manmade cousin), feeding ourselves will be no easy task.
One possible solution, according to the artist Paul Gong, is to eat garbage. In the imagined world of his Human Hyena project, resourceful humans could transform the taste and smell of spoiled food with a magnifying glass–shaped “Taste Transformer” utensil made from Synsepalum dulcificum (the so-called miracle berry that makes sour foods taste sweet) while inhaling stomach bacteria from hyenas that would allow them to successfully digest putrid food.
