These days China is breaking its records of contamination again, with levels that exceed the recommended by the World Health Organization by up to 8 times. In this video I show you how the center of Chengdu looks with 307 μg / m³ of harmful particles, a figure that, unfortunately, can be repeated many days a year in hundreds of cities in the country. However, it is important not to forget that this problem affects everyone (there are no borders in the atmosphere) and that not only should the Chinese be held responsible.
