9 Life-Support Systems for Humans.

I do not hold a position on any of these based on my own study, but I do recognize the potential catastrophic effects of not keeping an eye on these nine processes:

  1. Acid oceans (pH levels).
  2. Ozone (depletion).
  3. Fresh water (depletion).
  4. Biodiversity (extinction).
  5. Air cycles (nitrogen and phosphorus).
  6. Land resources (depletion).
  7. Climate control (change).
  8. Aerosol (loading).
  9. Synthetic chemical (pollution).

I want creation to penetrate you with so much admiration that wherever you go, the least plant may bring you the clear remembrance of the Creator … One blade of grass or one speck of dust is enough to occupy your entire mind in beholding the art with which it has been made.

– Basil the Great (329-379)
