Whales are sea animals. They live in the sea. They eat small fish and other sea animals. They can sing songs in the sea. One interesting fact is that they can jump high out of water. Another interesting fact is that some whales have teeth.
But now some kinds of whales are in danger because there is more and more water pollution and people even catch whales for meat, fat and oil. Or people sold whale parts to make candles and soap.
We should protect whales from human catching and killing. We should also learn more about whales and the rules on whale protection. I think people should stop putting rubbish into the sea. Only in this way can humans see more whales in the future.
