What, you haven’t received this month’s issue of The Bitter Southerner yet? An interview with E.O. Wilson finds him 90 years old and only semi-retired, living in Massachussetts.

In 2016, Wilson published Half Earth: Our Planet’s Fight for Life, in which he claims that if every nation sets aside half its landmass and waters for nature, then we can ensure the continuing existence of 85% of all species on the planet — including ourselves. The book garnered acclaim and criticism, but, like much of Wilson’s work, its central tenets have become more mainstream over time.
