Futurama Episodes

As Earth is unable to counter its rising temperature through the usual method (the dropping of a giant ice cube into the ocean), Gore leads an emergency conference in Kyoto, Japan, where Professor Farnsworth claims responsibility for the crisis. It seems love detoured him from observing proper emission standards on his prototype robot, and that could necessitate the destruction of all its “descendants.” That includes Bender, who resigns himself to having a farewell blowout before being blown up.
wikipedia.org summary:
The rapid increase in global warming is traced to a ventilation flaw that Professor Farnsworth failed to correct in his first robot prototype. As a result, all robots are ordered to be destroyed, but Bender refuses to go without a fight.
imdb.com summary:
Planet Express is hired to scoop a slab of ice from Halley’s Comet and drop it in the ocean to combat global warming. But when they find the comet all out of ice, the inventor of the environment, Al Gore, holds a Global Warming convention. There Professor Farnsworth reluctantly admits the process was sped up by the pollution emissions of all robots. This leads President Nixon’s head to invite all of Earth’s robots to the Galapagos Islands for a big party (during which they will be destroyed).
