One of the astronauts at the International Space Station (ISS) revealed that our planet is in a bad condition.
In an interview about the condition of the planet as seen from the ISS, Scott Kelly said: “When you look at the atmosphere on the limb of the Earth, I wouldn’t say it looks unhealthy, but it definitely looks very, very fragile and just kind of like this thin film, so it looks like something that we definitely need to take care of.”
He is due to return to earth in March, but was asked this month by CNN to describe the Earth’s condition if it were a human body.
He added: “There are definitely parts of Asia, Central America that when you look at them from space, you’re always looking through a haze of pollution.
“As far as the atmosphere is concerned, and being able to see the surface, you know, I would say definitely those areas that I mentioned look kind of sick.”
Mr Kelly’s remarks will be of concern as the atmosphere is the main reason life evolved and stays living on Earth.
It is why we have oxygen to breathe, fends of ultraviolet radiation from the sun, keeps the temperature right, makes the weather system that creates our water cycle, and also provides protection from incoming objects such as meteorites which burn up within it.
Studies by the Naval Research Laboratory show the density of the thermosphere has decreased more than 10 per cent over the last 40 plus years.
