According tomedia CNET reported that the new coronavirus outbreak has led to China, Europe and the United States, a number of cities to take “sealed” measures. Moreover, in some observable ways, all those who stay at home seem to be collectively taking on the responsibility of the global environment. NASA and the European Space Agency (ESA) first saw the impact through satellite data, which showed a sharp drop in nitrogen dioxide emissions from China since the “city-sealing” measure was implemented in February, most of which came from vehicles.
The European Space Agency’s Copernicus Sentinel-5P satellite also makes it easy to see that air pollution has been reduced to a similar extent in a few weeks in some northern Italian cities. The video below shows fluctuations in nitrogen dioxide emissions between January 1 and March 11.
“The reduction in emissions we are seeing is in line with Italy’s city-blocking measures, which have reduced traffic and industrial activity,” Klaus Zehner, mission manager for ESA Copernicus Sentinel-5P, said in a blog post. “
Similar effects have been shown in air quality reports around Los Angeles.
In addition, the environment of the famous canal city of Venice can be easily observed by taking a walk in the town. The water in the canals is sometimes known for its smell, and it is now clear that there are plenty of fish swimming and swans hanging around, enjoying the unusual peace and tranquility of the city:
In this new reality, some wildlife that has become dependent on human-provided food as its main source of food are now becoming more crude and bold. Deer living in Nara Park, Japan, were once fed by park visitors, but now hungry they leave the park and go to the city streets in search of food.
Similar chaotic scenes have been documented in places such as Huafuli, Thailand, where monkeys previously fed by tourists forage in the town and sometimes beat each other in the process.
“Sealing cities” may also affect the amount of carbon in the atmosphere. According to an analysis by Lauri Myllyvirta, a researcher at the Center for Energy and Clean Air Research, the reduction in coal and crude oil burning during the “city closure” period has led to a 25 percent reduction in China’s carbon dioxide emissions compared to the same period in 2019. “This is equivalent to about 100 tons of carbon dioxide, or 6% of global emissions over the same period,” Myllyvirta wrote.
