The new satellite images by NASA and the European Space Agency have shown a dramatic drop in pollution levels over China. Using pollution monitoring satellites, NASA has recorded a dramatic drop in the quantity of NO2, a harmful gas released by gas vehicles, power plants, etc. The economic slowdown and travel restrictions due to coronavirus outbreak are considered as the major factors behind the significant decline in air pollution. A map of the city shows a surprising decline in NO2 between January and the start of February. The reduction in air pollution is more significant and long-lasting than in previous years. The lockdown in the country has cleaned up the air faster than ever before in living memory.
