Plot

In the future, all forests on Earth have become extinct from careless environmental exploitation. As many specimens as possible have been preserved in a series of enormous greenhouse-like geodesic domes serving as closed ecological systems attached to large cargo spaceships, forming part of a fleet of eight "American Airlines Space Freighters", stationed outside the orbit of Saturn.
