❶What Is a "Non-Native Species"?
Non-native species are animals and plants from a different part of the world. They often create problems for the native animals and plants, or even take the place of other species. We usually think that all non-native species are harmful. But is this true?
❷How Does a Non-Native Species Arrive?
They usually arrive in new lands because of human activities. When we travel around the world, we sometimes carry species with us by accident. At other times, humans bring non-native species on purpose. They travel on our trains or ships far from their original homes. Now let's look at some examples of these non-native species.

・European rabbits in Australia
In 1859, an English settler brought 13 wild European rabbits into Australia because he wanted to hunt them for sport. However, some of the rabbits survived. After ten years, there were too many rabbits. They ate crops and many native plants. Other animals died because the rabbits ate all their food. There are now more than 200 million rabbits in Australia.
・Brown tree snakes in Guam
People brought brown tree snakes into Guam on ships by accident after World War Ⅱ. In just seventy years, the snakes ate most of the birds on the island. Nine of the eleven native forest birds in Guam disappeared completely.

❸Are All Non-Native Species Bad?
Scientists and governments around the world think that we should reduce the numbers of non-native species. But some of these non-native species actually help the lives of other species. On an island near Mauritius, the native giant tortoise died out. After that, many native plants on the island could not survive because they couldn't spread their seeds by themselves. The giant tortoise ate the fruit of the plants and spread the seeds in its feces. So at the beginning of the twenty-first century, scientists brought a non-native tortoise, the Aldabra tortoise, to the island. Now these tortoises are eating the fruit of the plants and spreading the seeds. Other non-native species can play similar roles in their new homes.

❹What's Important for the Environment?
Non-native species are often dangerous to other species. But in some cases, they play an important role in the new environment. Either way, we have to think as carefully as we can before we bring a species to a new environment. The impact of non-native species will be one of the greatest environmental problem of the twenty-first century. If we don't make the right choices today, the earth's natural environment will be in danger in the future.
