The Biosphere and the Lithosphere

Humans live in and from the biosphere. But in the first decade of the
21st Century, 85 percent of the primary energy consumed by the 6.7
billion humans comes from the lithosphere.

About 40 percent of this energy is oil. Another 40 percent comes from
natural gas and coal, and 6 percent more is from uranium.

This represents close to 10 billion tons of oil equivalent, extracted
every year from below ground.
