Make Earth! Play God!

The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed and self-regulating system taking heat and light from the sun. The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere and atmosphere. The biosphere is expected to have evolved, beginning through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.
