Antarctica(南极洲), the southernmost continent(大陆) on our planet, has become a more and more popular place for tourists to visit in recent years. Many travel companies now have special Antarctic tour plans. These tours usually begin from ports in South America, like Ushuaia in Argentina(阿根廷).
On an Antarctic tour, tourists can see the really amazing beauty of huge icebergs. These icebergs have all kinds of shapes and sizes. The icy places go on and on, making a super magical view. Penguins are one of the cutest things to see. There are different kinds of penguins in Antarctica, such as the Emperor Penguin(帝企鹅) and the Adélie Penguin(阿德利企鹅). Watching them walk in a funny way on the ice or swim nicely in the very cold water is something you'll never forget.
But Antarctic tourism also has some problems. The environment in Antarctica is very fragile and can be easily hurt by a lot of tourists coming. For example, if too many people walk around, it might bother the homes of local animals and plants. Also, the ships that take people there might accidentally leak(泄漏) oil or other dirty things, and this could damage the sea life.
So, while Antarctic tourism gives us a special chance to visit this faraway and wonderful place, it's very important that tourists and the travel companies do things to protect the environment. People should know how important it is to have tourism that doesn't harm the place when they think about going to Antarctica.
