Delhi becomes a gas chamber every year with the advent of winters, mainly due to stubble burning.
In Mexico City, Tehran, Kolkata, Bangkok, Shanghai, and hundreds of other cities, the air is no longer safe to breathe. In some cities, the air is so polluted that breathing is equivalent to smoking two packs of cigarettes per day.
Beijing residents joke that to get a free smoke all they have to do is open their windows!
With the approaching winter the air quality in many Indian cities, especially in Delhi, becomes a public health hazard. Something so fundamental as breathing easy can no longer be taken for granted. It's a wake-up call worthy of a civic revolution.
Poor air quality, which can be influenced by a variety of fumes, chemicals and allergens, is arguably the leading cause of triggers for most asthmatics in urban areas.
I'm from Los Angeles... I don't trust any air I can't see.
Air pollution is my biggest concern right now. Maybe because I live in Beijing, and in this city we have such severe challenges due to bad air quality. It has affected our daily lives and health. I do not go outdoors because of it. I desperately hope that we can improve the current situation.
In Washington, the air quality today was described as 'red.'...You know what 'red' is? It's bad for everyone. Not just old people, sick people and babies. When it's just bad for old people, sick people and babies, that's called a Republican budget.
If you live in the States, you see the windmill signal on your smartphone all the time. It's like living in Beijing air. You have to remember the blue sky.
