High levels of air pollution are one of the most serious problems in modern China. According to scientists, it directly affects the growth of such dangerous diseases as dementia, Alzheimer's disease and is the cause of many premature deaths.
Several projects are underway in China today to eliminate air pollution. So last year, 40% of enterprises were closed, the harmful emissions of which exceeded the established norms. Plans have also been announced to ban the use of non-electric vehicles. In October 2016, Dutch artist Daan Roosegaarde proposed a 7-meter tower designed to purify the air in Beijing. The tower sucks in polluted air, cleans it, and then “exhales” it back.
A year later, a 100-meter tower was built in Shaanxi Province in Central China, which has proven to be effective against smog. During testing conducted by scientists from the Institute of the Earth's Crust of the Chinese Academy of Sciences, the tower improved air quality in an area of 10 square meters. kilometers around the city of Xi'an, supplying 10 million cubic meters of clean air per day. Observing experts have noted a 15 percent reduction in air pollution in the area.
However, the tower in Shaanxi is far from the limit. Scientists hope to build an even larger 500-meter version in the not too distant future. She will be able to tidy up the ambient air on an area of 30 square meters. km, which corresponds to the size of a small town.
