“When you look at the atmosphere, in the limbo of the Earth (…) it looks very, very fragile and like a thin layer. It's something we definitely have to take care of, "Kelly said in an interview from the International Space Station.
The astronaut, who has repeatedly published images on his social networks about the atrocious pollution of the Earth seen from space, has affirmed that the most acute problem associated with the disappearance of the atmosphere is suffered by much of Asia and Central America. "When you look at them from space you always see a haze of pollution," he says. Also, Kelly has pointed out that if the Earth were compared to a human being, "definitely those areas would be sick."
As early as 2003, NASA warned that our atmosphere is thinning at an alarming rate as a result of carbon emissions, the effects being visible from space. According to studies by the US Naval Research Laboratory, the density of the thermosphere (layer of the atmosphere that extends between 80 and 500 kilometers in altitude) has decreased by more than 10% during the last 40 years.
Last November, NASA experts revealed that 4 billion years ago, the red planet was deprived of atmosphere due to the devastating impact of the solar wind. In this way, the red planet, despite containing enough water to contain bacterial life, was not able to maintain liquid water constantly as it either quickly evaporated or froze. The scientists warned that these same processes can be repeated in relation to Earth.
