Explain accelerated europhication. Mention any two consequences of this phenomenon

Explanation

Accelerated europhication is nutrient enrichment of water bodies due to human activities like passage of sewage.
Its consequences are :
Large amount of nutrients in waters causes excessive growth of planktonic (free-floating) algae, called algal bloom which impart characteristic colour to water bodies.
Depletion of oxygen content of water leading to the death of the aquatic organisms.
