Changes

The film opened opens with Mufasa (from The Lion King) declaring, “All things exist together in a delicate balance and so we must respect every living thing because we are all connected in the great circle of life”. This warning is followed by a montage of wildlife from all over the world set to the song "Circle of Life". Following the end of the song, the film transitions into animation.

The first animated segment of the film depcits depicts Simba drinking from a watering hole, until he is rudely interrupted by Timon and Pumbaa. The duo are removing trees in order to dam a stream and create "the biggest lake on the Savannah". The reason behind this construction , is that the twosome hope to construct and develop "Hakuna Matata Lakeside Village", where animals will be able to live the good life. Although Timon and Pumbaa are swept away by their idea, Simba notes that the animals downstream rely on the water that has now been damneddammed. In order to show them the error of their ways, Simba decides to tell a story about a "creature who sometimes forgets how everything is connected in the great circle of life".

Transitioning back to live action, Simba tells the story about the evolution of human society. Although they started out small (living in communion with the circle of life), humans eventually began to abuse the land. At this point in the attraction Hoover Dam is shown, which causes Timon and Pumbaa to decide that they need to plan bigger. After the brief interruption Simba continues his story, explaining that as human populations exploded they began to take up more and more of the land. As scenes from modern civilization are shown (including large scale farming, city life, skyscrapers and high rises), Timon and Pumbaa begin to get excited. Unfortunately, as Simba explains , in order to maintain their new cities, humanity needed more power. At this point, clips of Las Vegas and mass transportation are shown as Simba notes that life is not always about "having more and more of everything".

After Pumbaa informs Simba that he and Timon "had no idea", Timon asks the lion if everybody was ok with the damage being done to the environment. Simba tells them that no, people were not ok. In fact, once they realized what was happening they began to try to remedy the problems they had created. At this point a montage of conservationists, formerly endangered animals , and the creation of Earth Day are shown. Simba then notes that people have begun to clean up the water through treatment plants. Next, public transportation and recycling is depicted , and Simba asserts that in the future humanity is looking for cleaner ways to power their world, including solar and wind energy. Humans are also beginning to study the world’s creatures in order to help protect them.

As the film turns back into animation, Timon and Pumbaa are shown packing their bags so that they can help humanity. Simba stops them and asks if they are forgetting something. After a moment, Timon says he understands what Simba is hinting at, that "making the world a better place, starts in your own back yard". After this realization Timon and Pumbaa undam the stream, and claim that they are going to create the "Hakuna Matata All Ecological Family Village Resort " instead. At this , Simba roars in approval and the "Circle of Life " begins to play again. The film then closes with another montage which shows humans living in harmony with animals, and the circle of life.
