Hello everyone. Today, our group would like to talk about the threats to flora and fauna and what we can do to protect them.

As you know, there are many threats to plants and animals today. First, they face habitat loss because humans cut down forests to build houses. Second, pollution and climate change make it difficult for them to survive. Finally, illegal hunting is pushing many animals to extinction.

To solve these problems, we can do several things to preserve their habitat. We should build more nature reserves to give them a safe place to live. Besides, we need to raise people's awareness of protecting the environment, stop hunting, and plant more trees. If we all work together, we can save our beautiful Earth. Thank you for listening!
