What are 3 causes for the extinction of some wildlife species?
There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.
What are the causes of extinction of wildlife?
CAUSES OF ANIMAL EXTINCTION
- Demographic and genetic phenomena.
- Destruction of wild habitats.
- Introduction of invasive species.
- Climate change.
- Hunting and illegal trafficking.
What are 3 causes of animals at risk of becoming extinct or endangered?
They use the acronym HIPPO for Habitat destruction, Invasive species, Pollution, Population and Overharvesting [3]. The general consensus is that it is the P for people that is the primary cause of the dramatic declines in species worldwide.
What are the main causes of extinction in plant and animal species?
Species endangerment and extinction have three major anthropogenic causes—overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss. All three causes probably were factors in prehistoric as well as modern times.
What are the causes of the extinction of wildlife in India?
India has about 6.49% of all the fauna species in the world, he said. Factors like “competition, predation, natural selection, and human induced factors like hunting, habitat degradation” are some of the important reasons that have led to these extinctions, the Ministry said.

What are the causes and effects of animal extinction?
Extinction rates are accelerating The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
What are the causes of and solutions to animal extinction?
Causes of Extinction
- Exotic species introduced by humans into new habitats.
- Over-harvesting of fish, trees, and other organisms.
- Global climate change, largely due to the burning of fossil fuels.
- Pollution, which adds chemicals, heat, and noise to the environment beyond its capacity to absorb them.

What are the causes of wildlife extinction of Nepal?
Habitat destruction and over-exploitation are the main cause of extinction of wild life. a. Habitat loss, forest destruction and degradation: In Nepal the greatest threat to the conservation of wildlife comes from the activities of man which include habitat loss and forest destruction.
What causes animals to go extinct in the wild?
Predation, completion and diseases can also cause extinction in animals. It is natural for animals to compete for resources which are scarce. We find that in the process of evolution, many animals did compete for the resources and in the process many weaker animals were extinct.
Why are so many species on the brink of extinction?
Advancements in agriculture have especially impacted biomes and habitats that many species call home. In fact, up to one million plant and animal species face extinction, many within decades, because of human activities. Without drastic action to conserve habitats, the rate of species extinction will undoubtedly increase.
How many plants and animals are facing extinction?
According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), more than 1 million species of plants and animals are facing extinction – some with a span of as short as 10 years, and at this rate, their number will increase if we don’t do something about it.
What was the cause of the 6 th mass extinction?
This 6 th mass extinction is on us – Homo Sapiens. Over Hunting – The ivory of elephants, the fur and organs of tigers, the deliciousness of tuna and the supposedly medicinal effect of shark’s fin are some examples of why we have over hunted these animals to the point of extinction.
