The intentions are right, the mindset is wrong.
It will take two things to heal the earth: 1) interact with the planet as a living being and 2) design and dwell with cities, buildings, products and other human creations as organs in the body of Gaia. Climate change is nature's response to our attempts to halt her changes. Straining to freeze frame living processes into measurable and controllable quantities, we have blocked the veins and lungs of the earth. If we don't want Gaia's heart to stop beating, we have to stop attacking her with our mechanical mindset.
The moment we relate to Earth as You instead of It the world of fragmented parts becomes a living being. When we respond to Nature as a living being we can see what we share with all living beings: hope and fear, youth and aging, health and sickness, abundance and scarcity, and so much that is elusive and indescribable. We can see that we are interconnected with all beings, that our wellness is intimately related to the wellness of our neighbors. We can see that we share these life processes with earth and she shares them with us.
Certainly we need to reduce our carbon footprints and handprints. We need to recycle, build green, farm organic, power with solar and wind. But the tasks will be easier and the ways will be clearer when we dwell as living beings interacting with the living being of the earth. Then, instead of making futile attempts to heal a lifeless machine, we can heal the vital systems of a living being. Live for an hour seeing your home, your neighborhood and your city as living beings within the living body of the earth and see if that opens some pathways to your role healing the world.
