This attractive picture book enlarges on the metaphor 'spaceship Earth,' explaining that just as the space shuttle carries all the food, water, and oxygen the astronauts need, Earth carries all the food (minerals), water, and oxygen we need. It demonstrates the water, mineral, and oxygen cycles, showing that Earth makes a great spaceship, but tells readers that 'our job is to keep it that way.'
