This is the question that many of us will be asking in the coming decades as we transition to a sustainable global culture. As we evolve our understandings we will be able to bring deep definitions from first hand experiences in discovering and exploring our interdependence with all life.
We are at the beginning of this journey so it is a good idea to at least check out existing definitions for a good starting place. Wikipedia offers this definition:
Interdependence is a dynamic of being mutually and physically responsible to, and sharing a common set of principles with, others. This concept differs distinctly from "dependence" in that an interdependent relationship implies that all participants are emotionally, economically, ecologically and or morally "interdependent." Some people advocate freedom or independence as a sort of ultimate good; others do the same with devotion to one's family, community, or society. Interdependence recognizes the truth in each position and weaves them together. Two states that cooperate with each other are said to be interdependent.
The part about 'sharing a common set of principles' is probably where the rubber hits the road for some. Values and principles are usually rooted in one's unique culture so in order for 'interdependence' to be able to take root on a global scale there must be universal shared principles? That is where sustainability comes into the equation and allows all humans to adopt shared principles in relationship to our shared future well being.
The Earth Charter Initiative is celebrating it's 10th year since the release of The Earth Charter - Values & Principles for a Sustainable Future. You can learn about the how the Earth Charter was drafted in this Interdependent Project Radio interview with Steven Rockefeller who was chair person for the drafting committee or visit the Earth Charter website.
The Interdependent Project is celebrating the Earth Charter through promoting the 'Earth Scouts' - a new program for children that was launched by the Earth Charter US. There is a new network currently being created that will be launching soon that we have been supporting.
We are also celebrating through our ongoing commitment to share and promote the Earth Charter as a valuable tool for bringing all of us into harmonious interdependence from solid shared values and principles for a sustainable future!
