Tropical forests, often referred to as the „lungs of the Earth“ are essential for sustaining life on our planet. They provide clean air, water, and unparalleled biodiversity. While deforestation due to slash-and-burn agriculture, mining, and logging remains the most recognized threat, less visible but equally dangerous forces are at work. A new study reveals that nutrient enrichment – driven by human activities such as agriculture and fossil fuel combustion – poses a significant risk to the delicate dynamics of tropical forests.
