Doctors Warn of Delhi's Hazardous Air Quality

Dr. Chopra is worried about the air pollution in Delhi.

He says people have stopped wearing masks and children are still going to school on very polluted days.

He thinks everyone should take action to protect themselves from the harmful emissions in the air.

These emissions come from vehicles, chemicals, gases, dust, and smoke.

Dr. Chopra wants people to be more aware and take steps to stay safe.
