Air Pollution is responsible for around seven million deaths every year. Governments around the world have been trying to tackle it with a variety of measures. But now, the fight against air pollution is increasingly catching the imagination of artists and designers. In Al Hudayriyat Island in Abu Dhabi, a 7m high installation, Smog Free Tower by Dutch Studio Roosegaarde, bills itself as "the world's first smog vacuum cleaner." It purifies 30,000 cubic metres of air per hour and the dirt filtered from this urban smog is compressed into jewellery - Smog Free Ring - and sold to finance the project. In Delhi and Bangalore, AIR INK is "turning air pollution into ink solution" by capturing the black particles that float in the atmosphere and turning them into ink.
