2. What is endangered species? Endangered species is a population of organisms which is facing a high risk of becoming extinct because it is either few in numbers, or threatened by changing environmental or predation parameters. IUCN (International Union for Conservation of Nature) has calculated the percentage of endangered species.

3. The present situation There are 63000 kind of living things all over the world. But more than 19000 kind of living things are in danger. For example...... The mammals – 20% The birds – 12.5% The amphibians – 33.3%

7. What effect does it have on people? The endangered species will make people in danger. All the living things are consist of ecosystem pyramid. But if some animals become extinct, other connected animals will be endangered species, and then more and more animal will be extinct. Finally, the ecosystem will be disrupted and people can not live because people live in symbiosis with animals.
