Improved technologies to combat air pollution
Air pollution is a major issue around the world. It kills seven million people annually-one in every eight people that die around the world. And, of course, air pollution is a well-known and much-complained-about fact in Bangladesh. Few major global cities suffer from air pollution worse than Dhaka. During the dry season, when dust is especially bad, pollution levels can reach up to 16 times higher than the World Health Organisation's air quality guideline.
