Bet you didn't know you have two bodies. There's the one you're acquainted with -- the one you feed three times a day, the one that walks your brain around the house, takes you to work, the one that performs thousands of simple and complex tasks each day to keep you alive. This is the body you're most aware of, the one many of us try to keep healthy with thoughtful diet, exercise, rest, good health care. 
Your second body gives you water to drink, air to breathe, food to eat and millions and billions of resources. This body isn't yours alone. This body connects you to every other species, human and non-human. This second body is reeling from the effects and impact of so many first bodies. This second body is the earth.
Such is the discourse and unfolding epiphanies in "The World We Have: A Buddhist Approach to Peace and Ecology," by Thich Nhat Hanh, teacher, author, poet, peace activist and Vietnamese Zen Buddhist monk. More from Hanh's book:
... I have many other hearts. The sun in the sky is also my heart. If my own heart failed I would die instantly. But if the other heart, the sun, explodes or stops functioning, I will also die right away.
... We're imprisoned in our small selves, thinking only of having some comfortable conditions for this small self, while we destroy our large self.
I've been reading this little book almost daily and find it so rich, so full of meaning, I'm reading only a page or so at a time to meditate fully on the concepts.
Hanh's approach to the meaning of time and wealth, of how chasing after money ensnares us, embodied here, is a useful reminder on navigating the murky waters of a consumerist society where success is often defined by how much money you make:
We have constructed a system we can't control. It imposes itself on us, and we become its slaves and victims. For most of us who want to have a house, a car, a refrigerator, a television, and so on, we must sacrifice our time and our lives in exchange. We are constantly under the pressure of time. In former times, we could afford three hours to drink one cup of tea, enjoying the company of our friends in a serene and spiritual atmosphere. We could organize a party to celebrate the blossoming of one orchid in our garden. But today we can no longer afford these things. We say that time is money. We have created a society in which the rich become richer and the poor become poorer, and in which we are so caught up in our own immediate problems that we cannot afford to be aware of what is going on with the rest of the human family or our planet Earth.
