...The Earth Charter values and principles must be taught, contemplated, applied and internalized. To this end, the Earth Charter needs to be incorporated into both formal and non-formal education. This process must involve various communities, continue to integrate the Charter into the curriculum of schools and universities, and constitute an ongoing process of life-long learning.

Reads as though a study of these issues and placing them into context of Scripture to redirect those being taught back to God, might be a fruitful endeavor.

Take whatever door is open.
