As is known to everyone, animals are our friends. However, many kinds of animals are in danger now.
As far as I know, there are several reasons for this. First, humans cut down forests and pollute the rivers. Second, animals don’t have enough places to live in or enough food to eat, so the population of them are becoming smaller and smaller. What’s more, to make money, humans kill them for meat, fur and oil.
It’s time for us to protect endangered animals. As middle school students, what can we do First, We should prepare ourselves for protecting endangered animals even if we are only students. Second, we should call on everyone not to kill endangered animals. Third, we should advise the government to protect the homes of endangered animals.

Step 4:
Polar bears mostly live on sea ice. They are good at swimming. At birth, they weigh only a few hundred grams. But when they become adults, they may weigh as much as 900 kilograms. They can live for up to 25 years. They eat some animals in the sea. Nowadays, polar bears are in danger. There are many reasons for this. First, it’s because the Earth is becoming warmer and warmer and there is less and less ice. Polar bears are losing their homes. Second, people kill polar bears for their fur and meat, because their fur is thick enough to keep people
warm in cold winter. It is important for people to protect them. We must stop people from killing them.
