A study by J. Trepel et al titled “Global analysis suggests nitrogen deposition as an underestimated driver of vegetation greening” published on 20 July 2026 finds that our breathing and passing gas make trees grow. The paper is 12 pages with the main text about 8 pages. The remaining are references. The study attempts to model the effects of nitrogen (N) deposition on greening at a global scale from 2001 to 2024. It is not merely nitrogen in the atmosphere, nitrogen from hum
