Captain Planet and the Planeteers

The Planeteers are flying through a hugely populated city, soon finding a building about to fall. They call Cap, and he saves the building, but as they return to Hope Island, Gaia tells the Planeteers about the over populated world. She says people should have fewer children and listening to this upsets Wheeler. He goes out to wind surf when he falls off and is knocked unconscious. While unconscious, he has a dream about being on a populated island with humanoid mice, and he learns that the mice city is over populated, learning the negative effects of overconsumption due to overpopulation. He befriends a mouse named Piebald, and he shows Wheeler the effects overpopulation has had on their city. Wheeler escapes the island, then wakes up from the dream with a different attitude towards population.
