A man went on a trip to one of the most hostile environments on Earth, where the very air is hostile to life.
YouTube channel Fearless & Far made a trip to the spot, donning gas masks as they navigated the treacherous area.
There are plenty of places on earth where life has pushed back against the odds to survive in the most extreme circumstances.
Hydrothermal vents on the deep ocean floor pump chemicals from the deep inside the Earth into the cold water around them, and which despite seeming to be highly toxic are in fact oases of life in the deep ocean, showing just how resilient life can be.

But despite this, there is still a limit, as is shown by Dallol in Ethiopia, where lethal temperatures and geological processes create a lethal cocktail of chemicals and heat.
The YouTubers headed out there to take a look at the place, where hydrothermal activity has led to the mixture of salts, gases, and heat which proves so hostile to practically all life, never mind just human.

It's located in the Ethiopian Danakil depression, which the YouTuber described as being on three tectonic plates moving away from each other, as though 'the Earth is literally pulling itself apart'.
And if you wanted a picture of just how hostile this environment is, scientists even carried out scans on the area to see if any life at all could survive there.
Needless to say there are no large animals, no reptiles or mammals to be seen, though the YouTube crew said they did have to contend with some insects flying about.
But in the pools themselves surely there must be something on the microbial level? A particularly stubborn bacterium which insists on continuing to exist despite everything around it being completely hostile to life?
Scientists carried out tests, and in the toxic waters themselves, there is not even that.
Purificación López-García is a biologist at the French National Centre for Scientific Research, and a co-author on a study of the waters, and told CNN: “After analysing many more samples than in previous works, with adequate controls so as not to contaminate them and a well-calibrated methodology, we have verified that there’s no microbial life in these salty, hot and hyperacid pools or in the adjacent magnesium-rich brine lakes."

That's not to say that the area is entirely devoid of life though.
“What does exist is a great diversity of halophilic archaea (a type of primitive salt-loving microorganisms) in the desert and the saline canyons around the hydrothermal site, but neither in the hyperacid and hypersaline pools themselves, nor in the so-called Black and Yellow lakes of Dallol, where magnesium abounds,” said López-García.
“And all this despite the fact that microbial dispersion in this area, due to the wind and to human visitors, is intense.”
Extreme environments like Dallol can be useful to scientists trying to establish whether life is possible on other planets, as they show just how far life can be pushed to the limit and still persist.
