NEW DELHI - As the Indian capital witnessed an alarming increase in air pollution recent months, a young man wearing an oxygen mask and carrying a 20-liter plastic water bottle strapped to his back was an unusual attraction.
The oxygen mask's transparent tube was looped and fitted to the neck of the water bottle. Inside the bottle was an artificial tree in full bloom.
It appeared as though the man was breathing oxygen from a bottle similar to those used in Indian cities to carry home purchased drinking water.
