The transdisciplinary nature of conservation biology is pivotal to understanding the concept of near-term human extinction. The rate of environmental change impacts the habitat of all organisms, and loss of habitat underlies extinction. These concepts apply to all species, including Homo sapiens. The ongoing and expected rates of environmental change indicate human extinction in the near term, with loss of Arctic sea ice an important driving force.


Humans are able to sustain neither industrial civilization nor our species, Homo sapiens. Whereas many pre-civilized groups practiced sustainability, contemporary industrial civilization is not sustainable. Indeed, global industrial civilization underlies abrupt, irreversible climate change and also the ongoing Mass Extinction Event. We continue to overheat Earth, which is already at the highest global-average temperature with our species present. The rapidity of environmental change is increasing and will continue to accelerate with either increased industrial activity or, paradoxically, diminished industrial activity. This paper offers a path forward for all of us, and especially those who wish to educate others, in light of these daunting facts. If our species is destined for extinction, as all species are, then how shall we proceed? If our species is destined for extinction in the near term, as seems apparent, then how shall we proceed? What is the role of educators in the face of an existential threat?


Earth is in the midst of abrupt, irreversible climate change. The current global-average temperature of Earth is the highest ever with Homo sapiens present, and there is no demonstrated way to stabilize or reduce the planetary temperature. This paper describes a few means by which habitat for humans could be lost in the near future.
