The educational film TECHQUA IKACHI (Land and Life) relates history and prophecy to global warming. The teaching lesson plan is at http://techquaikachi.wordpress.com.

American history omits the most peaceful of societies. "Hopi" means "peaceful people", a thousand years at peace, far longer than any nation of America, Europe, Asia, or Africa.
The accuracy of Hopi prophecy is unmatched, directed specifically against mining and oil and proven accurate by the rising specter of global warming.
PART ONE: In AUTOBIOGRAPHY OF A HOPI (10 minutes), a Hopi farmer tells of his travels to hard times, to war, and back home to appreciation of traditional life close to nature.
PART TWO: In EARTH SPIRIT (34 minutes) indigenous people follow prophecy to resist oil and mining interests that exploit and pollute the land. News reports from similar confrontations faced by indigenous peoples around the world at techquaikachi.wordpress.com.
