What Does Endangered Mean?
What does it mean when an animal is an endangered species? First of all, a species is an animal, plant, fungus, insect or any living thing. When a species is found, researchers like to study it to know its habits and health — that way, when something is wrong, the researchers can tell.
What are the causes of endangerment?
Many reasons can cause endangerment, whether they be natural occurrences or human activity. Here are a few of those reasons: 1 Habitat Destruction: Some habitats are wiped out due to natural causes like floods or forest fires. If a species is already near threatened or vulnerable, something like this could cause endangerment. 2 Invasive Species: Invasive species are introduced to ecosystems to solve a problem or by accident from human activity. They can wreak havoc on an ecosystem and cause other species not to be able to find food, or the invasive species may kill the endangered one. 3 Illegal Hunting or Overexploitation: This is probably one you see most often in the news and media. People hunt animals illegally to gain money from the goods, and then the species is overkilled. 4 Pollution: Environmental pollution causes harm to animals. Think about the aquatic life that gets stuck in plastic bags and dies. 5 Genetic Loss: The genes in an animal may decline over the years, causing them not to be able to survive.
Why is the Endangered Species Act important?
Many animals today are endangered and are close to extinction. The Endangered Species Act was put out to protect animals near extinction and try to recover the population and habitat they are part of so populations can flourish once again.
What is critical endangered?
Critically endangered are a slight step closer to extinction in the wild than endangered are. Animals in this category will likely go extinct soon.
Why are invasive species introduced to the ecosystem?
Invasive Species: Invasive species are introduced to ecosystems to solve a problem or by accident from human activity. They can wreak havoc on an ecosystem and cause other species not to be able to find food, or the invasive species may kill the endangered one.
What happens to biodiversity when it is in danger of extinction?
A species’ health and population are essential for biodiversity, so when it is in danger of completely being wiped away from the earth, biodiversity drastically changes.
What percentage of a species is endangered?

Why are some species endangered?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaur s, for instance, lost their habitat about 65 million years ago.
What animals are threatened by humans?
Polar bears, mountain lions, and alligators are all predators brought into close contact with people as they lose their habitat to homes, farms, and businesses. As people kill these wild animals, through pesticide s, accidents such as collisions with cars, or hunting, native species may become endangered.
Why are mountain lions not endangered?
That means the habitat can support fewer mountain lions. Because enormous parts of the Sierra Nevada, Rocky, and Cascade mountain ranges remain undeveloped, however, mountain lions are not endangered. Loss of habitat can also lead to increased encounters between wild species and people.
How does human activity affect habitat?
Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms. This can happen in a number of different ways.
Do cheetahs have genetic variation?
Loss of genetic variation can occur naturally. Cheetah s are a threatened species native to Africa and Asia. These big cat s have very little genetic variation. Biologist s say that during the last ice age, cheetahs went through a long period of inbreeding. As a result, there are very few genetic differences between cheetahs. They cannot adapt to changes in the environment as quickly as other animals, and fewer cheetahs survive to maturity. Cheetahs are also much more difficult to breed in captivity than other big cats, such as lions.
Is the gray whale endangered?
For this reason, a species can be of least concern in one area and endangered in another.

What does "endangered" mean in the ESA?
Under the Endangered Species Act (ESA), plant and animal species may be listed as either endangered or threatened. “Endangered” means a species is in danger of extinction throughout all or a significant portion of its range. “Threatened” means a species is likely to become endangered within the foreseeable future.'.
Why are animal extinctions so high?
Although extinctions occur naturally, the current rate of plant and animal extinctions is much higher than the natural or historical rates. Habitat loss is the primary cause of higher extinction rates. Other causes include habitat changes, over-exploitation of wildlife for commercial purposes, the introduction of harmful nonnative species, pollution, and the spread of diseases.
What is an invasive species?
An invasive species is an introduced, nonnative organism (disease, parasite, plant, or animal) that begins to spread or expand its range from the site of its original introduction and that has the potential to cause harm to the environment, the economy, or to human health.

How long has the Earth been changing?
Since Earth began 4.5 billion years ago , it has been continually changing. Most often, this change is very, very slow—like the rising of mountains or draining of seas. Over millions of years, these gradual changes can impact individual species so much that they can no longer survive in the new conditions of their changing habitat.
What does it mean when an animal is considered endangered?
When an animal species is considered endangered, it means that the International Union for Conservation of Nature (IUCN) has evaluated it as nearly extinct, which means that a significant portion of its range has already died off and the rate of birth is lower than the species' death rate.
Why are whales endangered?
Even legal hunting, fishing, and gathering of wild species can lead to population reductions that cause species to become endangered. A lack of restriction on the whaling industry in the 20th century is one example. It wasn't until several whale species were nearing extinction that countries agreed to abide by an international moratorium. 4 Some whale species have rebounded thanks to this moratorium but others remain at risk.

Why are animals on the verge of extinction?
Today, more and more animal and plant species are on the verge of extinction because of a variety of major factors that cause a species to become endangered , and as you might expect, humans play a role in quite a few of them. In fact, the biggest threat to endangered animals is human encroachment on their habitats. 1.
What is an exotic species?
An exotic species is an animal, plant, or insect that is introduced into a place where it did not evolve naturally. Exotic species often have a predatory or competitive advantage over native species, which have been a part of a particular biological environment for centuries, because even though native species are well adapted to their surroundings, they may not be able to deal with species that closely compete with them for food. Basically, native species haven't developed natural defenses for an exotic species and vice versa.
