The only life left on the Earth after this will be single-celled organisms. 1 billion [note 2] 27% of the ocean's mass will have been subducted into the mantle. If this were to continue uninterrupted, it would reach an equilibrium where 65% of present-day surface water would be subducted. [91] 1 billion
The ablation and vaporization caused by Earth's fall on a decaying trajectory towards the Sun may remove Earth's mantle, leaving just the core, which will finally be destroyed after at most 200 years. [102] [103] Earth's sole legacy will be a very slight increase (0.01%) of the solar metallicity following this event. [104]: IIC
Estimates published in the early 2000s tended to predict that the population of Earth would stop increasing around 2070. [17] For example in a 2004 long-term prospective report, the United Nations Population Division projected that world population would peak at 9.2 billion in 2075 and then stabilize at a value close to 9 billion out to as far ...
Rosling states that this number is representative worldwide, the reason why the total number of children globally is now at a stable level of 2 billions. According to him, the so-called population explosion has already been overcome. The human population will peak at eleven billions, and stabilize at this level by the end of the century. [1] [2]

Long-range predictions to 2055 range from a population decline to 3.2 billion in the 'low scenario', to 'high scenarios' of 24.8 billion. One scenario predicts a massive increase to 256 billion by 2050, assuming fertility remains at 1995 levels. [6]
