Looking at these photos, you would not believe that the Earth was strongly revived during the Covid-19 epidemic: Rare miracle!

In the face of the complicated events of the Covid-19 pandemic, governments in many countries have strictly implemented measures to blockade and spread the social gap to reduce the spread of the virus. As of April 22, more than a third of the world’s population is at home and avoiding large crowds. A series of industries such as tourism and services have ceased operations, dragging the world economy down.

However, it is the absence of humans at this time that provides opportunities for nature to rest and recover. Changes in pollution levels, air quality, and the revival of the natural world have begun to appear in the past few months, since the first outbreak of the disease in Wuhan (China). .

When the Covid-19 outbreak broke out, Wuhan was the first blockade, followed by the entire Hubei province on January 29. Not long after that, many other provinces and cities in China also applied this measure to prevent the spread in the community.

According to satellite images of NASA and the European Space Agency, air pollution in the country of this billion people has decreased significantly in February 2020.

“This is the first time I’ve seen this significant drop across the board in a specific period of time,” said Fei Liu, an air quality researcher at NASA. “I am not surprised, because many cities in China have been cordoned off to fight the epidemic.”

NO2 emissions plummeted in Europe

Data from the European Space Agency’s Copernicus Sentinel-5P satellite has shown a sharp decline in NO2 in many cities over the past week.

NO2 (nitrogen dioxide) is a gas emitted from power plants, cars and industrial areas. It can be found in the Earth’s atmosphere and causes changes in weather patterns as well as adverse effects on human health.

From March 13 to April 13, NO2 levels dropped by 45% from last year in Madrid (Spain), Milan and Rome (Italy). Paris (France) also witnessed a 54% decrease in the past months, compared to the same period in 2019.

Noise is reduced, Earth is shaking less

According to data from the Royal Belgian Observatory, “cultural noise” – the sum of all the noise generated from daily life and human production – has been declining since cities began. blockade measures. As a result, the seismic vibration caused by this type of noise has also been reduced by up to 1/3, making it easier to study volcanic and earthquake activities.

According to Andy Frassetto – a seismic researcher at Washington Seismological Research Institute (USA), if the blockade order continues for a long time, earthquake aft detector can be more effective.

“You will get a signal with less noise so you will get more information about these events,” he said.

The canal in Venice is so clean that fish can swim underwater

After Italy declared a national blockade, the canals in Venice became clearer than ever. According to photos taken in March, people can easily see the seaweed at the bottom of the canal, as well as the sight of fish and swans swimming in the water.

According to Governor Luigi Brugnaro, the water in Venice became clearer because “less water transport activities on the water surface, allowing sediments to stay on the bottom”.

Animals return to habitats and areas where people frequent visits

About 95% of the Yosemite National Park in the US is defined as wilderness. This place welcomes 4 million visitors / year, especially in early spring when bears start to wake up from hibernation. This inadvertently made it difficult for bears to find food.

However, since Yosemite Park closed on March 20, 300-500 black bears have been seen “with more frequent frequency than usual”. American lynx also appear in vacant management quarters. Even, coyotes of North America are comfortable to cross the road without being disturbed by humans.

“The number of bears has quadrupled,” said Dane Peterson, zoo staff member.

Facebook user Andrew Thomas caught rescues of “invading” a McDonald’s in Wales on April 18.

Eleven new born rare back sea turtles are seen on the beach in Phuket (Thailand) before returning to the ocean on March 27. This is the largest number of sea turtles ever recorded here in 20 years, according to the Phuket Marine Biology Center.

In other countries of the world, the animals also turn back to natural habitats or spill out places where people still frequent.

For the first time in decades, the Himalayas can be seen from afar

Since March 24, India has frozen the country for 3 weeks to limit the spread of Covid-19

Many people living in northern Punjab state say the measure has reduced air pollution, so they can see the Himalayas from afar for the first time in at least three decades.

Suspecting the SARS-CoV-2 virus originates from bats, China has temporarily banned wildlife trade and consumption.

Immediately after the news that the SARS-CoV-2 virus could originate in the traditional South China seafood market, China announced a ban on all wildlife trade in the markets.

Before being closed on 1/1, Hoa Nam Seafood Market was a place of trading of wild animals such as wolves, civets, bats … to serve the needs of eating and drinking.

On February 24, China banned the illegal trade and consumption of wildlife.

Without people, beaches become cleaner, the water is cleaner

Miami Beach was so clear that Louis Aguirre had to say, “This is not the Caribbean or the Bahamas. This is Miami.”

Beaches and places with lots of traffic have been less polluted since the outbreak of Covid-19.

Correspondent Louis Aguirre of WPLG Local 10 in Miami (USA) has uploaded photos of a deserted beach. According to him, the color and clarity of the beach is “amazing”.

Mike Ruiz – a resident of Florida (USA) – expressed: “The water is clear, neon blue. You can see through the water to the bottom. I have never seen a water color so green during my filming years here. ”
