七、
Many kinds of plants and animals are in danger now. We should try our best to protect them well.
More and more plants and animals are dying out because they lost their living places or couldn’t find enough food. People cut down trees or kill animals to make money. Some factories pollute the rivers and lakes. That’s the reason why plants and animals are in danger.
For this serious reason, I think we should do something now. We should plant more trees, stop killing animals and close some factories to provide a better environment for them.
