“Agriculture changes natural ecosystems by replacing diverse habitats with large fields of the same crop. This reduces biodiversity because fewer species can survive in monocultures. To produce more food, farmers often use fertilizers. When rain falls, nutrient runoff carries nitrogen and phosphorus into rivers and lakes. This can cause eutrophication, where algae grow rapidly, use up oxygen, and harm aquatic life. As human populations grow, food demand increases, which expands farmland and irrigation. This increases land-use change and water use. A major environmental problem caused by agriculture is nutrient pollution. A realistic solution is sustainable farming, such as using buffer strips near waterways and reducing fertilizer use.” Mehr sehen
