Born to be Free
Orca whales（虎鲸） live in the sea. This is their home. In the sea, they can swim where they want to. There is no fence （栅栏） to keep them in one place. The orca whales are free.
In the sea, orca whales don't attack （攻击） people. When they are taken away from their home, it can be different. An orca is sometimes called a killer whale.
People caught orca whales and put them in pools. They trained them to do tricks. Sometimes the tricks went wrong. They attacked their trainers. Some trainers have died.
Now, some people say orca whales should not be taken away from their home in the sea. They are wild animals. In the sea they live with others. They can live a long time. However, they don't live as long out of their home.
The first orca that was caught only lived for a day. It just swam around and around in the pool. It was afraid and got much angrier little by little. It kept banging （撞击） into sides.
