In 2805, human civilization was highly developed, but the earth was no longer suitable for human habitation due to the massive increase of pollution and domestic garbage. People on earth are forced to leave their hometown by spaceship and embark on a long and endless journey to the universe. Before they left, they entrusted Buynlarge's company to clean up the earth's garbage. The company developed a robot called Wall E (waste distribution load elevator-earth waste subcontractor) to undertake this important task.
