Unsustainable agricultural practices refer to farming methods that deplete natural resources and harm the environment. For example, excessive use of chemical fertilizers and pesticides can lead to soil degradation and water pollution. These practices often prioritize short-term yields over long-term health of the land, making it difficult for future generations to grow food. Another common unsustainable practice is monoculture, where a single crop, like corn or wheat, is grown repeatedly on the same land. This reduces biodiversity and makes crops more vulnerable to pests and diseases. Ultimately, these practices threaten food security and the health of our ecosystems.
