The distant future. Humanity is no longer limited to planet Earth. However, humans haven't yet evolved out of our basic Earth-adapted forms. So, despite settling on all manner of distant worlds, human bodies need the same basic things we take for granted at home: food, water, breathable air, etc.
"Out there, though, among the stars on the living worlds we already know about and on other worlds that we haven't yet dreamed of, some will survive and change and thrive and some will suffer and die."- Octavia Butler, Parable of the Talents
The central theme of this contest is adaptation: using technology to adapt settings to our bodies, or vice versa—and what happens when those adaptations fail.
Your setting must either be, or be inspired by, a Kuiper Belt Object (KBO). T
