the river dried up?
Eutrophication
There are many reasons why a river dies. Eutrophication is one of these.
How does eutrophication happen? Garbage from households and other places
are thrown into the river. Soaps from various sources are also thrown into the
river. Nitrates and other industrial waste also find their way into the river. These
pollutants cause algae in the river and water lilies to loom and becomes plenty.
When algae blooms, the balance of life in the river becomes in danger. When the
balance of life is disturbed, algae decays and supply of oxygen in the river gets
lesser. The marine creatures living in the river die for lack of oxygen. When they
die, their bodies decompose and cause foul smell. Not long after this, the foul
smell gets worse. Soon the river dies.
