Explanation:
With many factories and businesses closed, combined with fewer cars on the road and fewer planes in the sky, our natural environment is recovering slowly.
China's 40% drop in NO₂ on 2019 levels for January and February in some areas equates to removing a whopping 192,000 cars.
The COVID-19 pandemic has caused industrial activity to shut down and cancelled flights and other journeys, slashing greenhouse gas emissions and air pollution around the world. If there is something positive to take from this terrible crisis, it could be that it’s offered a taste of the air we might breathe in a low-carbon future.
The World Health Organisation (WHO) estimates that about 3 million people die each year from ailments caused by air pollution, and that more than 80% of people living in urban areas are exposed to air quality levels that exceed safe limits. The situation is worse in low-income countries, where 98% of cities fail to meet WHO air quality standards.
Measurements from the European Space Agency’s Sentinel-5P satellite show that during late January and early February 2020, levels of nitrogen dioxide (NO₂) over cities and industrial areas in Asia and Europe were lower than in the same period in 2019, by as much as 40%.
