MARCOLI is one of the most paradisical planets known to exist, at least from a climatological perspective.  Warm seas and gentle breezes predominate.  Each of the planet's numerous lush islands is home to a population which is fanatically devoted to one of the many native plant species.  No Marcoline can eat any other food or wear clothing woven from any other material.  How they decided to specialize in such a strict fashion is a mystery, but apparently it works well enough, because all of the inhabitants remain healthy and adequately clothed.  One might expect each island to cultivate only its chosen fruit or vegetable, but that is unfortunately not the case.  Windblown spores germinate everywhere in the rich soil of Marcoli, and the plants seem quite intent on growing entangled with one another.  So growing their crops is not difficult for the Marcolines, but harvesting them is rather labor-intensive.
Worldwide friendly trade ensures that each agricultural product eventually reaches the island where it is most appreciated.  Visitors are advised to carefully research the islands they intend to visit, and attire themselves appropriately using exported goods available throughout the Sunderland sector.  Imported food and clothing is strictly prohibited.
