The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found. The study, titled the 2024 Living Planet Report, monitored ...
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.
Some of the first studies of the influence of climatic variables on wild mammals took place in the United States in 1960s. They analysed the impacts of severe winter weather events on the survival and reproduction of species such as Missouri cottontails and northern Montana Pronghorns., [42] [43] sometimes using radio transmitters.

Wildfire, drought impact wildlife According to the Pew report, rising temperatures linked to climate change have resulted in drought, extreme wildfires and change in the timing and location of ...
Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
Population control plays an important role in wildlife populations. Based on the species being dealt with, there are numerous ways populations of the wild are controlled. Wildlife contraception is the act of preventing reproduction in the wild, which subsequently decreases populations. An example of this includes the maintenance of deer ...
Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...
