And since our world's systems are composed of individual organisms, they have the capacity to change. We creatures adapt, our genes evolve, we can learn from experience. A system is ever-changing because its parts - the trees and fungi and people - are constantly responding to one another and to the environment. Our success in coevolution - our success as a productive society - is only as good as the strength of the bonds with other individuals and species.
If you have spent time with an infant, you might recognize the scene: A child is wailing, inconsolable, and you, the parent, have to go to the bathroom. Or eat. Or attend to a pot that's boiling over. But someone needs to watch the baby. Such urgent situations often call for innovation. In modern times, we might negotiate schedules with our partners, seek out affordable child care, or purchase "baby-tainment" contraptions via our phones.
