In some countries there is an overpopulation of pets such as cats, dogs, and exotic animals.In the United States, six to eight million animals are brought to shelters each year, of which an estimated three to four million are subsequently euthanized, including 2.7 million considered healthy and adoptable.
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.
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.
Blame lingering pandemic-era restrictions that make it harder for people to find a dog or cat they'd like to adopt.
In large part due to that overpopulation, the shelters’ euthanasia rates have increased significantly over the past year, with hundreds of animals — some of them adoptable — killed each ...
Shelters in New York and Los Angeles are nearing capacity as more and more people are dumping these animals while the world slowly moves back to normal. Meanwhile, puppy mills keep producing more ...
Population control is the practice of artificially maintaining the size of any population.It simply refers to the act of limiting the size of an animal population so that it remains manageable, as opposed to the act of protecting a species from excessive rates of extinction, which is referred to as conservation biology.
In reality, an animal that is not native to an environment may have advantages over the native ones, such being unsuitable for the local predators. If left uncontrolled, such an animal can quickly overpopulate and ultimately destroy its environment. Examples of animal overpopulation caused by introduction of a foreign species abound.
