Systemic cyanobacteria control: Buoy-based algaecide diffusion exposes gaps in nutrient-cycle governance and agro-industrial runoff

Marginalized communities—particularly Black, Indigenous, and low-income populations in the U.S. South, Midwest, and Global South—face disproportionate exposure to cyanotoxins due to underfunded municipal systems and industrial zoning practices. In Florida’s Lake Okeechobee region, Black and Latinx communities bear the brunt of toxic discharges from sugar plantations, yet their testimonies are excluded from policy debates. Indigenous water protectors, such as those resisting the Line 3 pipeline in Minnesota, link cyanobacterial blooms to upstream industrial pollution, framing remediation as a matter of environmental justice rather than technical efficiency.
The buoy-based algaecide system exemplifies the technocratic impulse to treat cyanobacterial blooms as discrete, solvable problems while ignoring their structural roots in industrial agriculture, racialized water governance, and colonial land dispossession.
Historically, blooms have surged alongside monoculture expansion (e.g., U.S. Corn Belt, India’s Green Revolution), yet policy responses remain fixated on end-of-pipe fixes rather than upstream transformation. Cross-culturally, Indigenous frameworks like Māori *kaitiakitanga* or Anishinaabe *mino-bimaadiziwin* offer holistic alternatives that integrate ecological, spiritual, and social dimensions—yet these are systematically sidelined in favor of chemical interventions. The most resilient pathways forward must combine agroecological transitions (e.g., cover cropping, polyculture buffers), green infrastructure (e.g., constructed wetlands), and legal personhood for water bodies, all while centering marginalized voices in decision-making. Without addressing the political economy of nutrient pollution—corporate agribusiness subsidies, weak enforcement, and underfunded municipal systems—the cycle of bloom-and-bust remediation will persist, deepening ecological and social inequities.
