Cat Eyes for Climate Change

How far would you go for climate change? NYU philosopher Matthew Liao has an outside-the-box proposal: Decrease energy by engineering humans to have meat allergies, fur, and yes, cat eyes.

Liao's argument is that if we're going to talk about geoengineering climate interventions like seeding the stratosphere with particles that reflect sunlight -- which we are considering -- then human engineering should be on the table too. James Fleming, professor of science, technology, and society, at Colby College weighs in on the history of this idea.
