Sixth Great Mass Extinction and M-Dwarf Habitability?

Sixth Mass Extinction

Where have all the animals gone?

Collaborators from Mexico and the US provide added evidence that we are entering a sixth mass extinction—triggered by human damage to the environment. The impact of the loss of species and the collapse of ecosystems could be much more devastating to humanity than climate change.

How should Christians respond to the sixth mass extinction? 

In this episode, biochemist Fuz Rana discusses the latest insights into large-scale species loss, explores the biblical basis for Christian environmentalism, and makes the case that the Christian story provides explanatory power for the extent of the damage that humans are causing to ecosystems around the world.

M-Dwarf Habitability?

NASA asserts that the most promising candidates for habitability are planets orbiting M-dwarf stars. M-dwarfs are less than half the Sun’s mass, less than 1/15 the Sun’s luminosity, and comprise 70% of all stars. The only remaining hope for finding a habitable exoplanet is to discover one identical to Earth. So far, the most Earth-like known planet beyond Earth is Venus.
