Cleaning up the Earth one block at a time

In the 29th century, Earth is a garbage-strewn wasteland due to an ecocide, caused by rampant consumerism, corporate greed, and environmental neglect.

Humanity is nowhere to be seen, having been evacuated by the megacorporation Buy n Large (BnL) to space on giant starliners, leaving trash compacting robots to clean up the planet, seven hundred years prior. The cleanup has failed and the last remaining active robot, named Waste Allocation Load Lifter: Earth Class (WALL·E) has developed a personality. WALL·E remains active by salvaging parts from other inactive robots and lives with his pet cockroach as his only companion in a large truck designed to carry the robots.
