I think the Siberian Tiger is one of the most popular animals that people like to see in the zoos. The reason is that they are strong and beautiful. But nowadays there are only 3000 or so Siberian Tigers in the world, and the amount of them is decreasing. Why? Because many forests are cut down and they have no places to live in. In order to protect them, we should build more natural reserves. Besides, we must make laws to stop people from hunting them.Lets try our best to save the strong and beautiful tigers.
