This unnatural balance damages the ecosystem and food chain. When too many of the same animal compete for a similar food source, many die from starvation. Others are forced to leave their natural habitats in search of food.

How does population growth affect species?
As the human population grows, we destroy more habitat, kill more animals for food, release more pollution into the atmosphere, soil, and water supply, all of which increase the rate of extinction of species. ... Modern rates of extinction were eight to 100 times higher , the authors found.
What happens when a species becomes overpopulated?
In ecology, overpopulation is a concept used primarily in wildlife management. Typically, an overpopulation causes the entire population of the species in question to become weaker, as no single individual is able to find enough food or shelter.
How does overcrowding affect animals?
WASHINGTON, Feb. 10 —Overcrowding in animal societies can lead to stress‐induced maladies—such as liver disease, heart trouble and sexual deviation—which serve as a natural form of population control. Minnesota jack rabbits suffer liver and heart ailments. Rats display abnormal sexual and social behavior.
How does overpopulation affect an ecosystem?
2 Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming.
How does human overpopulation affect the environment How does it affect the populations of other species?
Consequences number, on the one hand, deforestation and desertification, extinction of animal and plant species and changes in the water cycle and the most direct consequence of all in the form of emissions of large quantities of greenhouse gases leading to global warming.
What organisms are being affected by overpopulation?
“The polar bear, Florida panther and bluefin tuna are just a few of the species being pushed toward extinction by the world's rapidly growing population. People have taken away habitat for plants and animals, sucked up their water, and surrounded them with pollution, causing a global mass extinction crisis.”
Is animal overpopulation a problem?
Pet overpopulation is a serious problem. Animal shelters become overcrowded and are unable to care for the millions of homeless pets in the United States. Sadly, not enough people adopt their pets from shelters to help ease the crowding.
Why Pet overpopulation is a problem?
A primary factor that plays into pet overpopulation is allowing cats and dogs to reproduce with little chance of finding homes for their offspring. Another issue is when owners relinquish their pets because they either no longer want them or can care for them.
What causes overpopulation in animals?
Pet “overpopulation” encompasses two primary factors: (1) allowing cats and dogs to reproduce with little chance to find homes for the offspring and (2) pets being relinquished by owners who can no longer keep their animals, or who no longer want them.
How does overpopulation of animals affect the environment?
The environment suffers due to the strain from the natural activities of the overpopulated species. The results can be devastating as animals scrape for food and wander into unnatural habitats in search of something to eat. ... Overpopulated animal species lead difficult lives with limited resources.
How does overpopulation affect global warming?
More people means more demand for oil, gas, coal and other fuels mined or drilled from below the Earth's surface that, when burned, spew enough carbon dioxide (CO2) into the atmosphere to trap warm air inside like a greenhouse. ... During that time emissions of CO2, the leading greenhouse gas, grew 12-fold.
What are the negative effects of population growth?
It leads to the cutting of forests for cultivation leading to several environmental change. Besides all this, the increasing population growth leads to the migration of large number to urban areas with industrialization. This results in polluted air, water, noise and population in big cities and towns.
What happens to the population of species if they fail to adapt to these changes?
If it changes very rapidly selection may be inadequate to restore adaptation quickly enough, and the population will dwindle and eventually become extinct.
What are the main problems of overpopulation?
The rapid population growth rate has resulted in more problems such as food shortages, resource sharing problems, housing problems, education problems, and management problems in utilities.
