If it’s so hard to change the climate to suit humans, why not alter humans to suit the changing climate, philosophers from Oxford and New York universities are asking. They suggest humans could be modified to be smaller, to dislike eating meat, have fewer children and be more willing to co-operate with social goals.
Behavioural changes might not be enough, even if they are widely adopted, and international agreements for market solutions such as emissions trading are proving difficult to achieve, say Matthew Liao, of New York University, and Anders Sandberg and Rebecca Roache, of Oxford University.
They suggest hormone treatments could be used to suppress child growth, or embryos selected for smaller size. They say people who lack the motivation or willpower to give up eating meat could be helped by “meat patches” on their skin, which deliver hormones to stimulate the immune system against common bovine proteins.
“Henceforth eating ‘eco-unfriendly’ food would induce unpleasant experiences,” the authors say. Better-educated women have fewer children, so human engineering to enhance cognition could lead to fertility reduction as “a positive side effect from the point of view of tackling climate change”, the paper also argues.
