The new life form: Half of all life is on Earth Basement

Biologists explored an enormous living world buried below the surface of the Earth. Scientists estimate that nearly half the living material on our planet is concealed in or underneath the ocean or in rocks, soil, tree roots, mines, oil wells, lakes and aquifers on the continents. They refer this as "subsurface biosphere," a dark world where the sun and stars don't shine or Earth's basement.
Katrina Edwards, a microbiologist at the University of Southern California said that the organisms that live in this environment may cooperatively have a mass comparable to that of Earth’s entire surface resident and may provide keys to solving major environmental, agricultural and industrial problems. Such as geologists are considering whether to hoard some of the world's excess carbon dioxide, a major greenhouse gas, in a worldwide network of crevices below the seafloor.
Scientists say research on "intraterrestrial life" balance astronomers' hunt for "extraterrestrial life" around other stars and planets. Now scientist believes that some fact and discoveries not just found in the outside of the planet but also inside the planet and beneath us.
