What is Eutrophication?

Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication—which begins with the increased load of nutrients to estuaries and coastal waters.

Eutrophication of the world's lakes will increase the emission of methane into the atmosphere by 30 to 90 percent during the next 100 years, which will increase methane emissions equivalent to 18-33 percent of annual carbon dioxide emissions from burning fossil fuels contributing to climate change.

Stages of Eutrophication

Nutrient Enrichment

Water bodies are endangered by excessive richness of nutrients through agricultural & surface runoff

Early stages

This surplus nutrient expedites the growth of algae blocking sunlight over period of time

Hypoxia begins

Due to reduced sunlight, planktons and algaes start decomposing and absorbing oxygen from water bodies

A complete dead zone

At this point the water bodies has no oxygen and all the life forms are completely dead
