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 ...
Earth and the Moon will be most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than it is now. Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to Earth's surface. [216 ...
Modern proponents of the concept have suggested that overpopulation, population growth and overconsumption are interdependent [25] [26] [27] and collectively are the primary drivers of human-caused environmental problems such as climate change [28] [29] and biodiversity loss.
The researchers state that Earth has seen at least five periods of tectonic convergent cycles that resulted in continental assembly. Those coincide with large variations in global temperature .

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
Scientists warn that the Earth is just 15 years away from experiencing a "mini ice age" — something that hasn't happened in 300 years. Researchers in the U.K. created a new model of the Sun's ...
Parfit argues that the size of the "cosmic endowment" can be calculated from the following argument: If Earth remains habitable for a billion more years and can sustainably support a population of more than a billion humans, then there is a potential for 10 16 (or 10,000,000,000,000,000) human lives of normal duration.
