I disagree in part. Humanity per se is not the Cancer of the Earth. Rather, it is the money system, which is based on two rules: More is always better and What’s mine is not yours. In the real world (Gaia) the exact opposite rules prevail: Emough is enough (too much or two little of anything is toxic to any biological system) and that social animals thrive by sharing and compassion. Our human ancestors prior to the agricultural revolution and the invention of money knew these two rules very well. We forgot them—and that is when the Earth got cancer. Now it is terminal.
