Spaceship Earth
This spaceship would be fine for twenty years if needed to. A little less would be perfect for this ship. The two rooms with the water in them are the water filters. They use evaporation to clean the water sense evaporation is turning liquid to gas. The reason there is trees and plants and animals is for food and oxygen. Plants recycle co2 and turn it in back in to O, all the plants on my ship give food. The reason for animals is because animals are food, This place has crickets, pigs and cows. The way I recycle solid waste is compact organic waste and melt the metal and plastic for repurpose. Rocks we will probably smash but in to the water purifier room and let it sit there. Then the crew cabin is needed for company because you need it or you will go crazy.
