Yes, we are. And we are all dependent on the beneficence of Nature (or call it God if you want). We depend on air to breathe, fresh water, a source of food and shelter, and the company and assistance of our fellow humans in a great variety of ways.

This is also true of nations, and they would do well to remember it. They need each other.

Life is always a compromise between the desire for total independence and the inevitability of interdependence.
