The Volcanoes That May Have Started Life on Earth

The video explores the essential role of nitrogen in life and the challenges of its fixation. Despite its abundance in the atmosphere, nitrogen is largely inaccessible to most organisms. Natural processes like lightning and microbial activity fix nitrogen, but early Earth required non-biological means. Theories suggest volcanic eruptions and lightning played a crucial role. Recent research indicates volcanic lightning could have significantly contributed to early nitrogen fixation, providing a boost to the environment and potentially kickstarting life.
