High Quality Content by WIKIPEDIA articles! The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth`s surface, the rate of cooling of the planet`s interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun`s luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisis is being caused by technology and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to an equilibrium state.
