Hello, I'm Sumi Summaskanda from the BBC World Service.
This is the global story today.
The smog surging to dangerous levels in India and Pakistan.
Fires, cars and industrial pollution, all factors causing a huge smog cloud across South Asia.
It's now so big it can be seen from space.
In today's episode, we find out how the quality of the air we breathe contributes directly to millions of deaths worldwide.
Air pollution affects everyone.
So are governments acting fast enough to limit it and save lives?
With me today is Devina Gupta who has presented programs and covered business stories for the BBC.
And you're joining us from among the smog right now in Delhi, aren't you?
Yes, Sumi, I'm trying to breathe easy here.
Yeah, please do.
Trying very hard.
We're glad that we could have you on today, Divina.
And we also have Dr.
Gary Fuller from Imperial College London's medical department.
He studied air quality and its health impacts across the world.
