Nitrogen in the environment is a two-edged sword. It’s vital for crop production, but overabundance in its reactive form can pollute water and air, and harm human and ecosystem health. In this article, UK ecologist and biogeochemist Carly J. Stevens offers an easy-to-understand summary of how humans have dramatically altered the distribution of nitrogen on Earth in ways that are detrimental to human health and the environment. She suggests how further actions can reduce reactive nitrogen’s harmful effects while boosting crop production in nitrogen-deficient regions.
