With all the excitement about sending astronauts to Mars to explore the possibility of building human settlements on the planet, one question comes to the forefront: but what will they eat?
Today in The Conversation Canada, Lenore Newman at the University of The Fraser Valley and Evan Fraser at the University of Guelph write about their new book, Dinner on Mars. In it, they explore the innovative and spectacular approaches to food production that will need to come into play, from cellular agriculture to specialized greenhouses. “Imagining what agriculture could be like on Mars is a fascinating project,” they write, “but it’s when we think about how these technologies may affect life on Earth that this topic becomes extremely serious.”
