Andrew Lewin delves into the issue of the hypoxic zone in the Gulf of Mexico caused by runoff from the Mississippi River. Despite efforts to reduce nitrates and phosphates by 20% by 2025, it appears that targets may not be met. Andrew shares his personal and professional connection to this topic, having worked on the hypoxic zone early in his career. Tune in to learn more about the challenges facing the Mississippi River and the Gulf of Mexico and how you can take action to protect our oceans.

This runoff carries excessive nutrients, such as nitrogen and phosphorus, from agricultural activities along the river's basin. Upon reaching the Gulf of Mexico, these nutrients fuel the growth of phytoplankton, leading to massive algal blooms. Subsequently, these blooms die and sink to the ocean floor, where bacteria decompose them. This decomposition process consumes oxygen, creating a hypoxic or "dead zone" where oxygen levels are too low to support marine life. The size of the hypoxic zone in the Gulf of Mexico fluctuates annually but has been on an upward trend, indicating a worsening situation. This zone poses a significant threat to marine ecosystems by depriving fish, invertebrates, and other marine organisms of the oxygen they need to survive. The expansion of the hypoxic zone is a direct result of human activities, particularly agricultural practices contributing to nutrient runoff into the Mississippi River. Efforts to address the Gulf of Mexico hypoxic zone include implementing conservation practices to reduce nutrient runoff. These practices, such as cover crops, reduced tillage, and no-till farming methods, aim to minimize the amount of fertilizers and chemicals entering waterways. While some progress has been made in reducing nitrogen loads in the Mississippi River, phosphorus loads have worsened, indicating the need for more comprehensive and effective conservation measures. It is crucial to collaborate with local farmers to promote sustainable agricultural practices that protect water quality and reduce nutrient pollution. By investing in conservation programs, providing technical assistance, and incentivizing farmers to adopt environmentally friendly practices, we can mitigate the harmful effects of nutrient runoff on the Gulf of Mexico ecosystem. Ultimately, addressing the Gulf of Mexico hypoxic zone requires a multi-faceted approach that prioritizes environmental conservation, sustainable agriculture, and the protection of marine biodiversity. Efforts to reduce nitrogen and phosphorus in the Mississippi River have been crucial in addressing the hypoxic zone in the Gulf of Mexico. However, as highlighted in the podcast episode, these efforts have not met the targets set to reduce the nutrient loads entering the river system. Despite some implemented practices showing promise, such as cover crops that help absorb excess nutrients to prevent runoff, there are other practices exacerbating the issue. One concerning practice mentioned in the episode is the over-fertilization of corn acres along the Mississippi River. Farmers, driven by the belief that more f
