VERY interesting! I have had many (ever-changing) thoughts about these types of topics myself and I find your viewpoints bearing common themes as I've discovered...
For example, what if the EARTH is really symbolic of our HEART? If the earth is screwed up, then that is only a reflection of our hearts being screwed up :P
I've heard and experienced that it is possible to not need food/water to survive. What if the "food" we really crave is spiritual food not natural food? If we fill ourselves with spiritual understanding, then we won't be hungry for natural food. Even Jesus said "I have food that you know not of and My meat is to do the Father's will" I believe the things we observe and feel in the natural are only a reflection of the reality in the spiritual realm. Most of what we do and react to and desire is driven by our natural understanding which leaves us like a dog chasing his tail. But if we can understand spiritual things, then we can rightly interpret any situation and create the change we want/need.
Anyway, all the best.
Fruit On buddy!
