New Blog: What can Israel's water story teach us? OK, so it seems Israel has figured out how to move from water scarce to water abundant in one generation. Can the rest of us? I suppose this shouldn’t be surprising since Jews lived sustainably in this land for thousands of years until they were driven out by the Romans in 70 AD.

She sought to distinguish the difference between sovereignty and self-determination, and encouraged the audience to read the United Nations Declaration on the Rights of Indigenous Peoples. Her parting words were to commit to regenerate ourselves through devotion to deep love, loyalty and worship of our sacred Mother Earth. Check out the rest of my article here.
