What major river system's pollution significantly impacts the Gulf of Mexico's water \[ \text { quality? } \] Ohio River The Mississippi River The Red River The Missouri River

The Mississippi River is infamous for being one of the major river systems whose pollution drastically affects the water quality of the Gulf of Mexico. As it flows through various states, it collects runoff containing fertilizers, pesticides, and other pollutants from agriculture and urban areas. This influx leads to serious environmental issues, including harmful algal blooms and a dead zone in the Gulf, where oxygen levels are minimal, threatening marine life. In terms of real-world application, understanding the relationship between the Mississippi River's pollution and the Gulf of Mexico can inform policies aimed at reducing agricultural runoff. Various initiatives, like establishing buffer zones and improving waste treatment processes, are crucial. By implementing better practices, we can work towards enhancing water quality and preserving marine ecosystems for future generations.
