These microbial communities have learned to live at Earth’s most extreme reaches

Global Warming is a hoax! We humans do not even know how much live their is on our planet! 
These extreme microorganisms are amazing stuff!

"These types of microorganism were once considered ‘extreme’ forms of life, but research over the past couple of decades has shown that as much as 70% of all microbes on Earth live in similarly harsh environments. Other studies have shown that life is abundant in places long deemed inhospitable, such as deep sediments under the oceans, the cold deserts of Antarctica and even the stratosphere. ... And others, like those found buried deep in the sludgy ocean floor, live so incredibly slowly that they might survive to be hundreds or thousands of years old, eating and reproducing infrequently ... Early hints that life existed deep within Earth’s crust first surfaced in the 1920s, when oil prospectors noticed that groundwater around their oil fields was laced with hydrogen sulfide and bicarbonate, which are both made by bacteria. In the 1980s, microbiologists began counting the microbes in cores brought back from the Deep Sea Drilling Project — a large-scale effort to explore the sea floor — and were astounded by the numbers. ... It wasn’t until the early 2000s, with the launch of an expedition devoted solely to exploring life in the deep biosphere, that scientists started to understand the biology of these deep-sea-dwelling microbes. ... Most of these edge dwellers can’t be studied in a lab: they simply don’t grow in culture. ..."

These microbial communities have learned to live at Earth’s most extreme reaches: Researchers are uncovering the survival strategies of microorganisms found in rocks buried deep beneath the ocean floor.
