Quizplus · Accepted Answer

The widespread use of pesticides and fertilizers initially resulted in dramatic increases in crop yields. However, in the long-term, pests developed resistance to pesticides, which decreased their effectiveness and led to further chemical applications. Additionally, the excessive use of fertilizers led to soil degradation and erosion, negatively affecting agricultural productivity.
