A species is endangered when its numbers have fallen so dangerously low that it risks becoming extinct — gone from the Earth forever , like the dodo or the woolly mammoth . Extinction is a natural part of life's history , but today species are disappearing far faster than normal . Scientists estimate the rate is now up to 1,000 times the natural background rate , and almost all of this speeding-up is caused by human activity .
Scientists keep a careful watch on which animals are in trouble using a system called the IUCN Red List . It sorts species into categories — from "least concern " for animals doing fine , through "vulnerable " and "endangered ", to "critically endangered " for those closest to vanishing . This list helps the world know which animals need help most urgently .

Animals become endangered for several main reasons . The biggest is habitat loss , as forests are cleared for farms and cities . Others include illegal hunting and poaching for fur, horn , or ivory ; pollution that poisons land , rivers , and seas ; invasive species brought from other places that outcompete or eat native animals ; and climate change , which shifts the conditions animals have always depended on.

💡 Conservation is the work of protecting nature . It includes creating wildlife reserves , breeding endangered animals in zoos , passing laws against poaching , and restoring damaged habitats .
The good news is that conservation can work , and there are inspiring success stories . In 1986, only about 620 mountain gorillas remained in the wild . Thanks to protected national parks , anti-poaching patrols , and teaching local communities to value the gorillas , the population has climbed back to over 1,000. In New Zealand , the kakapo — a plump , flightless parrot — has recovered from just 51 birds in 1995 to over 250 today , each one given its own name and watched over.
