A Clemson philosophy argued recently that he wants all humans to die off as a punishment for their treatment of animals and the environment. Since his article was published in the New York Times, he has refused to defend his opinion.

According to a report from The College Fix, Clemson University Professor Todd May recently called for the end of human existence and has refused to defend his argument. May argued that humans do far more bad than good. What are humanity’s worst crimes according to the professor? These include oppression of animals and destruction of the environment.

The New York Times column, which was titled “Would Human Extinction Be a Tragedy?” was published in late December. In the column, May weighs humanity’s positive contributions to the world against its negative contributions.
