MADRID.- A spectacular exhibition now presides over the circular courtyard of the Feria de Madrid site, from today until the end of the World Climate Summit COP25. It symbolises the predicament of major cities with high pollution rates. Visitors to COP25 will thus be able to experience the air in the regions being simulated by the 'Pollution pods’ under the banner of climate awareness. The levels of pollution in cities such as New Delhi, London, Sao Paulo and Beijing will be recreated through a series of interconnected geodesic domes forming a ring.

It is a laboratory simulation that emulates, through artificial aromas and scents, the particles of nitrogen and sulphur dioxide and the carbon monoxide present in the air of the cities with the greatest population, industry and vehicle density. The experience enables the visitor to pass through increasingly polluted cells and understand the health risk of breathing polluted air, a reality for millions of people around the world, in addition to becoming aware of the actions that worsen this situation.

The first place to experience the work of visual artist Michael Pinsky, the creator of this immense exhibition, was the Norwegian Starmus Festival. Since that first appearance, more than 200,000 people have been able to smell and feel this polluted atmosphere through this great piece currently being exhibited in Madrid - and previously exhibited in public spaces in cities such as Geneva, Manchester, New York, Paris and Vancouver - as a wake-up call to institutions, governments, organisations and the general public.
