Question

Which of the following activities were significantly affected by the Kolleru Lake pollution?

• A. Urban settlements
• B. Industrial catchments
• C. Bird migration
• D. Agricultural farms

Answer 1

The correct option is C Bird migration

$\bullet$ The Kolleru Lake is home to 193 migratory bird species, but recently it faced a drastic decrease in the number of birds due to the practice of aquaculture, industrial pollution, and removal of weeds from the lake.
$\bullet$ The villagers burned all aquatic plants and water weeds that served as food for migratory birds to build new aquaculture ponds.
$\bullet$ The number of birds slowly decreased due to loss of fodder in the lake. Besides, the industries had also polluted the entire lake with the effluent discharge ultimately making it inhabitable for the migratory birds.
