While you are & # 39; walk, in a street with vehicles and people or in your house patio, under the sound or calm surface (according to its case), large ecosystems are as rich as Amazon and more than all the seas Amazon. planet
But this world has almost not been explored and looked at you need powerful microscopes.
"It's like we've found a new new resource for our planet," said Karen Lloyd, a researcher at the University of Tennessee in the United States.
Lloyd is one of the sciences that participated in her; Deep Carbon Theater Project, Deep Carbon DCO Survey.
Over 1,200 science from 52 countries gave data for this ambition A project that studies life under the ground. And the first production was presented this week at an American Geo-American Union meeting, in Washington (SA)
"Nearly 70% of microbanks are on Earth under our feet", Lloyd confirmed.
"This changes our idea of where life is on Earth, and takes care of it from the surface, where there are trees, whales or dolphins, to the underground world where there are many much of life on the planet. "
Despite the great heat, the lack of light, the animals is scarce and the great weight, and succeed in the life of this world underground.
The sciences thought that the underground organisms are a representing 15,000 to 23,000 million tonnes of carbon, hundreds of times larger than the content in everyone.
In order to reach this estimate, the sciences dried on the surface of the earth and gave samples in excess of 5 km deep, both underground and underwater.
From these samples, the researchers used to live organisms in organisms based on organisms.
And based on these records they used models to estimate the total number of underlying biomass.
"Although these samples are only bigger bullet points, we have examined sufficiently different ecosystems to find a reasonable estimate of the carbon content of this form of life," said Rock Colwell, an eco- microbial systems at the University of Oregon.
Microbes and minerals
Researchers have estimated that there are between 2,000 and 2,300 million kilometers in the deep biosphere, almost twice as many of the seas.
The most common organisms such as prokaryotes, that is, membrane membrane, which includes bacteria and archaea, unicellular animals known as a different advanced history from a drug.
But scientists also find eukaryotic organisms, that is, microbial or multi-cell organisms with cells in which they are gloomy in shells.
The earthquakes of this deep world can not take advantage of sunlight for energy, so they do not use photoynthesis but compare them alone.
In other words, they get chemical energy and nutrition from the surrounding minerals.
According to scientists, some of the concepts that live thousands of years move only when there are changes to tectonic pests, earthquakes or breaks.
