Nitrogen is essential to life, and almost 80% of the atmosphere is made up of this element. But mostly living organisms can’t access it in this form. On this episode, we’re going to explore the natural process of nitrogen fixation, which transforms atmospheric nitrogen into a form our bodies can use. We’ll also look at a scientific breakthrough that made it possible to create synthetic nitrogen fertilizer. It supported the Green Revolution and our current global population of 7.2 billion people. However, there are some negative effects that come with overuse and misuse of these fertilizers. Join us for this short science explainer.
