Operation Cleanup was a operation plotted and executed by the Buy n Large corporation, for the purpose of cleaning earth of pollution.
History
In the late 21st and the early 22nd centries, earth was suffering immense pollution from waste and toxification caused by extreme consumerism. In the early 22nd century, Buy n Large noticed the downside to their succesful economic domination, as earth was slowly dying. They plotted a plan to clean earth; deploy mass robot labor to compact and centralize the trash on earth and relocate humans on huge starliners for five years. However, this plan proved to be far too optimistic, as earth was declared too toxic for life and humankind had to stay in space. All the WALL-E units were deactivated, except one remained active.
New life
For uknown reasons, earth was able to support life once again in the 29th century, 700 years after humankind left.
