A fact rarely appreciated is the extent to which the prevalent human diseases are concomitant symbols, metaphorically continuous with the ongoing ecological disaster of our disharmonic stewardship of the earth. The rapacious increase in cancers, for example, reflects the just-desserts of our cavalier poisoning of the planet, blythely shitting where we eat to use the turn of phrase. The incident statistics of the last two centuries reflect the larger human theme of our own disowned progenerative forces run amok. We destroy to build build build but hardly if ever look to the appropriateness, relative necessity or suitability of our addiction to technological constructivism, much less do we pay any heed to the consequence of our inventions and impositions on pre-existing natural orders.
Like ourselves at the level of herd, our cells at the level of the cancerous individual have lost the checks and balances of disciplined and wise limitation. The rate of cell reproduction overtakes what can be harnessed and employed to maintain any kind of coherent status quo. The formation of infrastructure runs riot, regulatory forces are handicapped, and destruction of macro-organism thru site-specific micro-proliferations is the result. There is no better symbol of KOYAANISQATSI (hopi word for "life out of balance") than our destructive overgrowth and mismanagement of resources come flesh in the cancer diasthesis.
The other major diseases follow suit in their niggling poetic aptness for the times. Diabetes is greed for the sweetness of life at the expense of the other flavours of real nutrition. Cardiac disease is the hardening of the vessels as a maladaptation against the leaking of plasmic life force energy at the expense of heart. These are not fanciful connections drawn to suit a whim. If we fail to grasp the fact that we are poster-children for the particulars of human crime against the planet and ourselves we're doomed to extinguish all hope for healing in the conflagration of our stubborn ignorance.
