Recurring floods, fires, droughts, severer hurricanes, global warming, rising sea levels, species loss: Visible evidence of a collapsing ecosystem and imminent end of life on Planet Earth — unless urgent transformations occur, and within sufficient time! Ironically, most of the life-threatening "natural disasters" the world is experiencing are human-induced — ecological outcomes of a seriously flawed understanding of human nature, and the ways of life that we have built around that misconception. If, therefore, we are to successfully and permanently reverse climate change, and if humans and nature are to thrive and flourish into the infinite future, the logical and necessary starting point is to set right the generally accepted but seriously flawed understanding of human nature that has given rise to unsustainable exploitation of the Planet. For, in matters pertaining climate change, prevention is obviously better than cure. The surest prevention, of course, is Global Culture Transformation — beginning with the way we define ourselves and the purpose of our life.
