HWC, caused by competition for natural resources between human and wildlife, influences human food security and the well-being of both humans and other animals. In many regions, the number of these conflicts has increased in recent [ when? ] decades as a result of human population growth and the transformation of land use .
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.
Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population , though it may concern individual nations, regions, and cities.
In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
Most of the exponential human population growth worldwide is occurring in or close to biodiversity hotspots. [6] This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity.

Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
In 2022, a stray dog was seen wandering with a severed human arm in its mouth, leading the Jackson Police Department to discover a decapitated body in a nearby abandoned house in the woods outside ...
Conflicts between people and wildlife arise in certain situations, such as when an animal's population becomes too large for a particular area to support. Human-induced changes in the environment will often result in increased numbers of a species. For example, piles of scrap building material make excellent sites where rodents can nest.
