Which of the following is a consequence of agricultural runoff?

Agricultural runoff refers to the flow of water, typically from rain or irrigation, that carries fertilizers, pesticides, and other chemicals from agricultural fields into nearby waterways. The consequence of this process includes the introduction of harmful chemicals into local water systems. These pollutants can take the form of excess nutrients, such as nitrogen and phosphorus, which can lead to a variety of environmental issues including algal blooms, which deplete oxygen in the water and create dead zones, adversely affecting aquatic life.

The impact of agricultural runoff extends beyond just chemical introduction; it plays a significant role in shaping the quality and health of local ecosystems. Therefore, recognizing how agricultural practices can negatively influence water quality through runoff is essential for environmental stewardship and the development of sustainable agricultural practices.
