Question

Explain how agricultural practices have disturbed the ecosystem.

Answer 1

Agricultural practices have disturbed the ecosystem in several ways. Clearing forest areas for agriculture and human settlements degrades land and destroys habitats. Overgrazing by cattle removes vegetation, leading to soil erosion. Excessive use of chemical fertilizers alters soil chemistry and kills beneficial microbes, contaminating water sources as well. Over-cultivation exhausts the soil of nutrients, while excessive groundwater use for irrigation lowers the water table. These activities cause loss of fertile topsoil, desertification, and overall ecosystem imbalance, threatening biodiversity and sustainable agriculture.
