Captain Planet and the Planeteers (1990)

Season 4: Episode 6

The soft-hearted Planeteers have been collecting homeless animals from around the world, and when Gaia sends them on a trip to return the endangered species to the wild, they find that the animals' habitats are in severe danger. To Gaia's surprise, instead of releasing the animals, the Planeteers return to Hope Island with a Geocruiser so full that Noah would be proud.
