Nine out of ten people in the world breathe polluted air according to the World Health Organization, and the French company AirVisual, based in China, exposes it on a global map that allows to see in real time the level of pollution of any point on the planet .
The visualization combines state air measurement stations, satellite information and AirVisual's Node monitor network to update the cloud of pollutants circulating around the world.
The 3D map offers a color scale based on the level of PM 2.5 particles in each region, tiny specks of dust dozens of times smaller than the diameter of a hair that easily enter the lungs and, from there, can enter the bloodstream.
"We use this measure because it indicates the most serious threat to health," explained Yann Boquillod, founder of the company. "According to the WHO, seven million people die each year due to this type of air pollution," he added.
The talks against climate change held in November in Marrakech provided the ideal setting to launch the AirVisual interactive, although its creator claims that the map aims to focus on the absorbed levels of these harmful substances.
Of course, Boquillod assures that a relaxation in the activities that produce PM 2.5 will also imply a reduction in the emission of greenhouse gases. On the other hand, burning biomass to heat homes, for example, produces less carbon dioxide than natural gas, although it does produce more particles that are harmful to health.
The regions painted in more reddish tones, those with levels above 200 micrograms per cubic meter (ug / m3), are mainly located in East Asia, although there are exceptions that are also not related to human action. In the Sahara desert, concentrations of these particles are usually high due to sandstorms in the area. However, the highest measurements are seen in heavily industrialized areas.
