I am Andy, a Grade 8 student from Sunshine Middle School. I love wild animals, and my favourite wild animal is the tiger. Tigers are big and strong. They have orange fur with dark stripes. They can run very fast. Besides, they are able to swim and climb.
Sadly, there are not many tigers left in the wild now. They are in danger because hunters catch them for their fur, bones or other parts of the body. Also, some people want to make the forests smaller and smaller in order to have more space for farms and buildings. This will lead to less and less space for them.

So it’s time for us to take action to protect tigers. We’d better prevent the hunters from hunting them. What’s more, I think we can build more reserves for them.
Animals are our friends. It’s our duty to help them live a happy life in the wild.
