The article discusses how overgrazing harms biodiversity and land in dry areas. By studying the relationship between biodiversity and ecosystem health, researchers found that grazing affects biodiversity differently depending on the area's dryness. In wetter areas, biodiversity responds to grazing in a certain way, while in drier areas, it responds differently. Biodiversity also influences how grazing impacts ecosystem health. To maintain biodiversity and ecosystem health in drylands, sustainable grazing practices should consider local climate and grazing intensity.
