(29.9.2015) In 2012 a philosopher named Matthew Liao co-authored a paper that proposed altering human biology to combat climate change. In the paper, Liao and his colleagues propose a number of possible changes to human biology to help us combat climate change. When the paper came out, it got a lot of attention. Some people thought that Liao and his colleagues were trolling the academic community or that it was some sort of early April Fools joke.
