The book’s central point, much criticised since, is that “the earth is finite” and the quest for unlimited growth in population, material goods etc would eventually lead to a crash.
Right now, we are all whizzing through space on an amazing planet which we call the Earth. This planet is a discrete entity, whose finite life support systems are all on board. These systems are powered by energy from the sun, its “mother ship.” This residential program is referred to as “Sunship III” because it’s all about our Earth, the third planet from the sun.
Students [are] invited to the McKeever Center to tour the Sunship, or “SOL” — the “Ship Of Life.” During their experience they will examine its “System Of Life” by learning about the concepts of energy flow, cycles, and interrelationships; its “Sections Of Life” by learning about natural communities; and finally their own personal “Styles Of Life.”
