This youtube channel primarily supports my courses in Environmental Biology at Fullerton College. And now (summer 2023) I am transitioning the channel to provide support for my interest in planetary biology. Planetary biology is a perspective that considers life in terms of the whole planet. It is a hard science outgrowth of the ingenious perspective advocated in the early 1990s by James Lovelock and his sublimely assertive advocate, Lynn Margulis.

I have been sharing my thoughts on planetary biology since the late 1990s at my website, planetarybiology.com. There are several kinds of resources there including: information about my book, "Principles of Planetary Biology;" my personally-curated list of exoplanets; my free exoplanet explorer simulator called, "exoExplorer;" a handy technique for approximating the location of any star's circumstellar habitable zone; and a discussion forum for related topics.
