Biosphere

The biosphere includes everything living on Earth. It is also known as ecosphere. Currently the biosphere has a biomass (or amount of living things) at around 1900 gigatonnes of carbon. It is not certain exactly how thick the biosphere is, though scientists predict that it is around 12,500 meters. The biosphere extends to the upper areas of the atmosphere, including birds and insects

In a general sense, biospheres are any closed, self-regulating systems containing ecosystems. This includes artificial biospheres such as Biosphere 2 and BIOS-3, and potentially ones on other planets or moons.

 Biosphere of the Earth 
The earliest known evidence of life in Earth includes biogenic graphite dated as far as 3.7 Billion years old. Life is scattered all throughout the surface of the Earth, from the polar ice caps to the equator, exhibits a life of some kind.

 Extents of biological life
