Crutzen's Hypothesis

Crutzen's Hypothesis suggests that human activities, especially the use of nitrogen-based fertilizers and fossil fuels, significantly increase the amount of nitrogen compounds in the atmosphere. This excess nitrogen can lead to environmental issues like smog formation, acid rain, and changes in the natural balance of ecosystems. Essentially, human actions are disrupting natural nitrogen cycles, which can have far-reaching impacts on air quality, climate, and biodiversity. Crutzen's work highlights the importance of understanding and managing nitrogen emissions to protect environmental health.
