The Coronavirus crisis has a huge positive impact on the air as air pollution is clearing drastically over the past couple of weeks.
This is something that scientists observe from space using earth-observing satellites. They measure the traces of gases such as nitrogen dioxide, carbon dioxide, and methane in the air which are the main reason for the polluted air on Earth.
Nasa and the European Space Agency have released the data from these satellites (from Sentinel-5 satellite to be exact) and the nitrogen dioxide levels over China and Italy are extremely low – and they still remain low. Spanish cities Madrid and Barcelona are also following this pattern and the nitrogen dioxide levels in the air are dropping.
Usually, the nitrogen dioxide oxidizes in the air when wood and coal is burnt. Another cause is cars, trucks, and other vehicles. It is dangerous for our health – most specifically for our lungs.
Polluted air is proven to cause respiratory issues as well as cancer. The World Health Organization says that the polluted air is responsible for seven million deaths every year.
The good thing is that the pollution clears up almost overnight when the sources of the pollution are removed – and because of the pandemic the air is clearing up very easily.
