Endangered & Extinct Species
Understand why some animal species become endangered or go extinct: habitat destruction, hunting/poaching, pollution, climate change, and invasive species, and know examples like the giant panda, mountain gorilla, Amur leopard, and the now-extinct dodo and thylacine, using the IUCN Red List as the system scientists use to track threatened species
What a learner can do afterwards
- Defines endangered as a species at risk of extinction
- Names at least 3 causes of species becoming endangered
- Gives at least 3 examples of endangered or extinct animals
- Knows the IUCN Red List exists as a tracking system

An endangered animal is one with so few members left that the whole species could disappear forever. Extinct means the species is already completely gone. No dodo or thylacine has walked the Earth for a long time, and none ever will again.
Animals become endangered for several reasons. Habitat destruction happens when forests, wetlands, or grasslands are cleared for farms, roads, and cities, leaving animals without a place to live. Hunting and poaching kill animals for meat, fur, or other body parts, sometimes faster than the animals can reproduce. Pollution poisons the water, air, and soil animals need. Climate change shifts the temperatures and weather patterns species have adapted to over thousands of years. Invasive species, animals or plants moved into a new place by people, can out-compete or eat native animals that have no defense against them.
The giant panda lost most of its bamboo forest to farms and towns, but decades of protection have helped its population grow back to about 1,900. The mountain gorilla, found in the misty mountains of central Africa, is still threatened by habitat loss and poaching. The Amur leopard, one of the rarest cats on Earth, has only around 100 left in the wild because of hunting and a shrinking forest home. Two animals did not survive: the dodo, a flightless bird, went extinct less than a century after sailors reached its island home, and the thylacine, a striped hunting marsupial from Australia, was hunted until the last one died in a zoo in 1936.
Scientists use the IUCN Red List to track how much danger a species is in. It sorts animals into categories, from 'least concern' up to 'critically endangered' and finally 'extinct,' so conservationists know which animals need help most urgently.
Endangered means at risk of disappearing forever; extinct means already gone, and habitat loss, hunting, pollution, climate change, and invasive species are the main threats scientists track on the IUCN Red List.

Learn and try: Endangered species conservation
Endangered means a species may vanish forever. Giant pandas, mountain gorillas, and Amur leopards are all in danger. Their numbers fell because forests were cut, hunters took too many, or the climate shifted. Small groups face big risks.
Conservation means fighting back. Rangers guard parks, vets heal hurt animals, and laws ban hunting. Zoos breed rare babies for release. When people act, species can climb back.
Learn: Threats to biodiversity
Many dangers press on wildlife at once. Habitat loss bulldozes homes, pollution poisons water, and plastic traps sea life. Hunters and poachers take rare animals for money. New pests and diseases arrive with travelers. Climate change scrambles seasons animals trust.
The dodo and the thylacine are gone for good, warnings from history. But knowing the threats points to fixes. Name the danger and you can plan the rescue.
Species At Risk Education Kit
Scientists track trouble with lists. The IUCN Red List sorts species from safe to gone, like a hospital chart for the planet. Red means urgent, and thousands of animals sit in red rows. The list tells rescuers where to rush first.
School kits bring the list to life. Students map habitats, count species, and debate fixes. Learning the system is step one.
