If humans are the cells of the cancer on the body of Gaia,

a. Despite what John McKenzie said, there is not likely to be a radical humanectomy. A lot of cells are going to be left behind by the surgery, and the humanoma will balloon again. And Gaia's ability to heal herself has been radically lessened by mining, petroleum pumping, etc., and it takes a LOONNNNNNNNNG time for Gaia to grow such new organs, if indeed it is possible at all.

b. Not only do the cancer cells multiply asymptotically and consume the available food supplies, but they starve and extinctify (medical term there) many other beneficial cell (animal) lines. And the human cancer cells create large quantities of toxins, in the form of industrial waste, etc., many of which Gaia cannot nullify before they kill off still other valuable cell lines.
