This has led to an immense crisis in freshwater biodiversity, with species extinction rates four to six times higher than their terrestrial and marine cousins.
Fertilizing grasslands increases productivity but decreases plant diversity by intensifying competition for light, allowing faster-growing species to outcompete others. Artificially added light can counteract these effects, suggesting that controlling nutrient enrichment is crucial for conserving biodiversity in managed grasslands.
