Many causes lead to animals, plants and insects being placed on the endangered species list. Thousands of mammals, reptiles, birds and other living things are in danger of extinction because of various environmental changes, diseases and humans. It is too late to save those that are already extinct, but many can be helped by reducing these negative factors.
Global warming increases temperatures and causes severe climate changes. Melting ice caps devastate the natural habitat of animals, such as polar bears, dolphins and seals. Many sea creatures, such as salmon and other fish ,are sensitive to water temperature. Coral responds to the increased temperatures by releasing their own algae into the ocean which often causes the reefs to die off. Rising sea levels lead to flooding which impacts land mammals as well. The increase of droughts caused by global warming can wipe out food sources. The Pika, a small rabbit species native to the U.S., cannot adapt to rising temperatures and has already abandoned one-third of its previous habitat in search of colder temperatures.
Whalers, poachers and hunters has caused a decrease in populations of animals, such as humpback whales, chimpanzees, gorillas, snow leopards and giant pandas. Although laws have been passed to protect many animals, they continue to be threatened to be killed for their bones, skin and fur or be illegally traded aspets. Sometimes, humans introduce non-native species, leading to imbalances in the ecosystem, which is happening with jaguars. Some animals may be vulnerable to these new predators. This also creates increased competition for food sources.
Deforestation has caused habitat loss to many animal species. Deforestation can be caused by logging and mining and also natural causes, such as forest fires. Species that are native to jungles and tropical rain forest, such as orangutans and tigers, are endangered by habitat loss. Maned three-toed sloths and the slender loris are endangered solely because of deforestation. Asian elephants, giant otters and mountain zebras are all threatened by habitat loss.
Rabies in East Africa is killing Ethipoian wolves while many bird species are being devastated by Avian malaria. Koalas are being threatened by the spread of Chlamydia and AIDS. Domestic animals can also spread diseases to wild animals. Pollution from acid rain, oil spills and the dumping of toxic chemicals into the water affects many species of frogs, birds and fish. These animals, particularly frogs, are also endangered due to the use of pesticides and fertilizers that weaken their immune systems and kill their eggs.
Habitat destruction, disease, pollution, invasive species, poaching, and penises. Especially penises. Don't forget penises.
Mostly deforestation and human encroachment
The rainforests where they live are being chopped down.
The reasons are pollution and a virus attack on frogs.
There are many reasons, most important are pollution, destruction of their habitat and collection for pet trade.
Habitat loss, pollution, acts of man, etc...
Habitat destruction.
only some frogs are endangered but this frog is endangered
it depends on which species you are talking about but not all frogs are endangered
Yes. Some poisonous frogs are endangered such as the corroboree frog.
They are endangered because this type of frogs habitat has been lost and medications were made frog these frogs
There are many types of frogs that are endangered. On Earths' Endangered Creatures List under amphibians there are presently 2294 endangered frog, toads, salamanders, etc.
Exstinction
yes they are.
all over!
yes
they went endangered in the 1990's
There are many different endangered frog species but i cant name them all.
growling grass frogs
