Thank you for a very interesting and eye opening blog. I read it with great interest. Tragic to learn that no less than 20% of premature deaths in Dhaka are caused by the pollution. You mention that recognizing the brick sector as a formal industry and encouraging diversification to energy-efficient products is the way to go - but how can that be achieved concretely? What should be the first, second and third step be towards formalization and diversification? How did China go about in adopting cleaner technologies? Curious to learn more, and thanks again for highlighting this issue.
