Reading the following passage to answer the questions.

2. Why are many animals extinct
The relationship between humans, animals and plants.
Human, animals and plants are created to have a good relationship with each other to make a better and beautiful life. Without animals and plants, humans cannot eat anything and probably we cannot live anymore. Without humans, some animals and plants also cannot live for long time because no one takes care of them.
Therefore, we humans must protect animals and plants to grow up with us together. Currently, many animals are extinct because there are many reasons that make them live in short life such as being killed for people's collections or by stronger animals, pollution, natural disasters, the changes of weather. Therefore, many people are doing more work to help, take care, protect and prevent animals from being extinct.
