This film calls for an appreciation for the natural world. The main character, Freeman Lowell, attempts to salvage whatever is left of the Earth as we know it today, which is contained in three greenhouse-like domes. Only there does vegetation grow lusciously and freely in all shades of green.
Freeman Lowell, lobbyist for a reality in danger of being destroyed, stands for all things nostalgic and human. Therefore, it is only appropriate for him to eat fresh fruit and vegetables, as these are readily available from the “nature” that has been held captive in the domes. This is a reference to the beginnings of man as a gatherer. Technology does not interfere with the pure and basic activity of nourishment. By eating unprocessed and healthy foods, Freeman Lowell represents good.
In contrast, his companions on the ship who do not question the harm in destroying the last remnants of nature are shown to eat synthetic foods. Noticeably artificially-coloured in their pastel tones, these small dry bits resembling hors d’oeuvres are neither appetizing nor familiar. By their mere bland appearance, they can be imagined to be without texture, pleasure or taste. They differ greatly from earth’s fruits and vegetables and therefore also clash in all that they stand for.
It is worthy to note that although what the characters eat is different, meals are still a social activity in this movie. People still meet to eat—even if they have opposing views—just like today's world.
