I demonstrate how to calculate the mass of oxygen in the atmosphere. And I talk about nine reasons why the accepted values may be wrong.
Stories and commentaries about environmental awareness and ideas for how to make the world a better place.
Oxygen depletion compared to carbon dioxide emissions. Author’s note: This isn’t one for my usual audience. It’s super heavy on the science.
