    Earth in a few billion years could likely resemble present Venus. One billion years from now, about 27% of the modern ocean will have been subducted into the mantle. If this process were allowed to continue uninterrupted, it would reach an equilibrium state where 65% of the current surface reservoir would remain at the surface. [58]

    The Earth will naturally become uninhabitable due to the Sun's stellar evolution, within about a billion years. [147] In around 1 billion years from now, the Sun's brightness may increase as a result of a shortage of hydrogen, and the heating of its outer layers may cause the Earth's oceans to evaporate, leaving only minor forms of life.
