Human overpopulation is likely to lead to more extinctions of species due to increased habitat destruction, as expanding urban areas, agriculture, and infrastructure encroach on natural ecosystems. Additionally, the heightened demand for resources such as food, water, and energy intensifies exploitation of wildlife and their habitats. Pollution and climate change, exacerbated by a larger population, further threaten biodiversity, making it increasingly difficult for many species to survive. Consequently, as human activities expand, the delicate balance of ecosystems is disrupted, leading to a higher risk of extinction for vulnerable species.
Sudden changes in environmental conditions.
It is important because the timing suggests a strong correlation between human arrival and the extinctions, indicating that human activities likely played a significant role in driving these extinctions. This can provide valuable insights into the impact of human presence on ecosystems and the importance of conservation efforts to prevent future extinctions.
The rate of extinction is faster.
If a predator is eliminated from an ecosystem, its prey population will likely increase significantly due to the lack of predation pressure. This can lead to overpopulation of the prey species, which may result in overgrazing or depletion of resources, ultimately destabilizing the ecosystem. Additionally, the increase in prey may negatively impact other species and the overall biodiversity of the area.

Typically, cold-blooded animals are more likely to survive mass extinctions than their warmblooded counterparts. Animals who are lower in the food chain are also more likely to survive. Mass extinctions, however, vary in their causes, and so also vary in their effects.
The most famous of course is the extinction of the Dinosaurs 65 million years ago in the Cretaceous - Tertiary period.Prior to that there was the Triassic - Jurassicextinction about 205 million years ago. Although this is a disputed impact extinction, it is still one of the theories.The most devastating was the Permian - Triassicextinction 250 million years ago in which 96% of all marine species and 70% of all land species were killed including insects. This extinction event is believed to be a series of small extinctions over time or 2 large extinctions , there are several theories from climate change to impact.The further back you go the harder it is to estimate extinctions because of the lack of fossil records but two more that are listed are.The late Devonian extinction 360-375 million years ago, again a disputed impact event, but a comet or meteor is among the favoured.And Ordovician - Silurian extinction 440-450 million years ago.
Mass extinctions occur when the conditions on Earth change faster than species can adapt. Since humans have greatly changed the conditions on Earth and continue to change them at rapid rates, a mass extinction is a likely possibility if nothing is done to reverse or stop the changes (mainly the amount of carbon dioxide being released to the atmosphere). Another common cause of mass extinctions are extraterrestrial which cannot be predicted and are somewhat spontaneous.
One successful solution to global overpopulation is providing access to education, particularly for women and girls. Educated women tend to have fewer children and are more likely to use contraception. Additionally, promoting family planning services and ensuring access to contraceptives can help address overpopulation.

Typicaly the species will plateau and the population will reduce as competition for increasingly scarce resources increases. This can (but will not always) lead to extinction in extreme situations, but the most likely outcome is a much lower population and the resulting evolutionary bottleneck.
A generalist species would be more likely to survive because they are able to adapt to different resources and conditions. Specialist species, on the other hand, rely on specific resources and may struggle if those resources are destroyed.
