Excessive nutrients in waterways negatively impact the environment, the people and the economy.
Consequences of excessive nutrients in the water:
Higher cost of drinkable water and health risks
Lower food security and diminished access to clean water
Reduced recreational & economic benefits from activities using bodies of water like fish farming, tourism and diving
Water reserves suffering irreversible environmental changes
Severe loss of biodiversity
Freshwater pollution by phosphorus and nitrogen represents very high costs for government agencies
$4.3 Bn spent annually in the USA on dealing with freshwater pollution (Kansas State University)
$157 Bn spent annually in the USA on dealing with environmental and health damages (Environmental Research Letters)
According to the International Nitrogen System:
“We must halve the amount of nitrogen we dump into the environment by mid-century
or our ecosystems will face epidemics of toxic tides, lifeless rivers, and dead oceans"
