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.
Estimates published in the early 2000s tended to predict that the population of Earth would stop increasing around 2070. [16] 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 ...
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
Global population decline would begin to counteract the negative effects of human overpopulation. There have been many estimates of Earth's carrying capacity, each generally predicting a high-low range of maximum human population possible. The lowest low estimate is less than one billion, the highest high estimate is over one trillion. [21]
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 United States population grew by 3.3 million people this year, the highest increase in more than two decades that was primarily driven by immigration, according to data released this week by ...

Artist's concept of the Earth 5–7.5 billion years from now, when the Sun has become a red giant. While the future cannot be predicted with certainty, present understanding in various scientific fields allows for the prediction of some far-future events, if only in the broadest outline.
