The document discusses the main causes of endangered animals, which are destruction of habitat, pollution, and hunting/fishing. Habitat is destroyed when forests are cut down for furniture and development. Pollution harms underwater animals who ingest plastic or have trouble breathing. Hunters decrease populations by killing animals for food, crafts, and money. Some species that are endangered or nearing extinction are listed. If animal populations continue to decline, it could severely disrupt food chains and ecosystems. Protecting animals is important both for environmental balance and because many people enjoy wildlife through pets and food. A proposed solution is setting up breeding centers to increase endangered populations before releasing them back into nature, while also stopping illegal hunting.
