Question

UNIT 1: SPARROWS - HERE TODAY, GONE TOMORROW?
Read the following:
1. What were once upon a time seen
in millions throughout the country,
are today seen only in certain
pockets of India? House sparrows.
Why so? Conclusively, there have
been no studies to identify the
exact cause behind the sudden
decrease in their numbers, but
studies conducted in Jharkhand,
India have pegged the decrease in
sparrow count to be an alarming 80
