Nutrient loading refers to the process whereby excess nutrients, such as phosphorus (P) and nitrogen (N), enter bodies of water and deposit within the sediment. Nutrient loading commonly occurs as a result of human-generated changes to land cover causing an increase in nutrient availability. Agricultural runoff presents one of the largest contributors to nutrient loading, especially within Southern Ontario, Canada. Because higher than normal levels of N and P within bodies of water can affect the health of humans, non-human animals, and the environment, a One Health approach is needed to address the issue of agricultural nutrient loading. This article outlines a cost-effective, grassroots action designed to reduce excess nutrient levels within the Niagara River. It involves introducing floating wetlands to filter excess agricultural nutrients and improve water quality, generating healthier conditions for humans, non-human animals, and the environment.
