NASA images show coronavirus shutdown has cleared China pollution – By Tania Snuggs (Sky News) / March 1 2020
The US space agency says travel restrictions and the closure of businesses contributed to the drop in nitrogen dioxide.
NASA has published satellite images which show a dramatic decline in pollution levels over China, which the US space agency says is “partly related” to the coronavirus.
It claims there has been a significant decrease in nitrogen dioxide (NO2) – a noxious gas emitted by motor vehicles, power plants and industrial facilities – due to the economic slowdown following the outbreak.
COVID-19 started in the Chinese city of Wuhan, which was placed in lockdown from 23 January, with residents not allowed to leave and businesses ordered to close to reduce the spread of the disease.
