Video: A Visit to Ascension Island - The World's First Artificial Ecosystem
Located in the middle of the Atlantic Ocean, Ascension Island is literally a thousand miles from anywhere. When it was first discovered back in 1501, there was just one tree to be found anywhere on the island. But later, in the 1800's, naturalist John Hooker began to transform the place, bringing in non-native species of plants. Today, it is a mix of its original landscape and new vegetation, and it as you'll see in the clip below, it is a much different place.
