An endangered species is one that's likely to disappear if we don't take action. This can happen because their homes are being destroyed or there aren't enough of them left.
When people talk about an endangered species, they're usually talking about animals like pandas or elephants. You might hear on the news that a certain animal has been put on the list of endangered species in its country. This means that scientists think it needs protection to survive. The government and conservation groups work together to help keep these animals safe by setting aside habitats for them, stopping hunting, and making sure there's enough food and water. They also try to educate people about why these animals are important and need our care.
