Answer 1

Answer:

1) The birds migrate to the subcontinent to escape Russia's cold weather. The Yamuna wetlands become a host to these birds until the climatic conditions are stabilized in their homelands.

2) High amounts of heavy metals in water can cause several health effects such as reduced growth and development, cancer, organ damage, nervous system damage, etc. More than 800 million litres of largely untreated sewage is pumped in the Yamuna each day.
