Answer 1

This pollutes the air and causes problems for residents who live in the vicinity of such dustbins. Maids washing courtyards throw  the dirty water on the roads in front of the houses instead of throwing  it into the gullies. ... People here are frequently seen littering the roads by throwing rubbish  from running cars.
