Human-caused nutrient runoff, primarily nitrogen and phosphorus from agricultural fertilizers, sewage, and industrial waste, is the dominant driver of global harmful algal blooms (HABs). #WetTribe #TidetotheOcean #NutrientRunoff #HarmfulAlgalBlooms

#Nutrientrunoff from upper agricultural regions of the MississippiRiver watershed creates a hypoxic “dead zone” in the Gulf of Mexico. The 2017 dead zone was the largest measured since 1985, at 8,776 mi. 75B tons of soil are lost to erosion annually on fertile lands, a financial loss of $400B/year
