3 Crucial processes: Study suggests humans can breathe thanks to volcanoes, tectonics and cyanobacteria

(Natural News) Researchers from the University of California, Riverside and Rice University have tied up multiple complex processes to come up with one comprehensive theory answering how oxygen became ubiquitous on Earth. In a paper published in the journal Nature Geoscience, the researchers described how tectonic activity –the shifting of Earth’s outer crust – led to the formation of volcanoes that spewed massive amounts…  » READ MORE
