It is unrealistic to think that fruitarianism proposes an immediate total eradication of such needless harm and death, but I do see it as a method to greatly minimize such, and over time as the consciousness of humankind expands toward its spiritual potential, I do not believe that such a goal is at all unrealistic.
My vision is to see the whole world embrace this concept. I believe that once humankind has inevitably done so, other species (YES!) will naturally follow suit.. So instead of looking up to other species as examples as to how we should eat and live (Sadly most often the case today), other species will be guided and influenced by us, and ultimately the chaotic bloody balance of nature as it currently exists, will evolve into a harmonious peaceful balance where all species will be able to live their lives without fear of this insane dog eat dog, kill or be killed competitive ruthless insanity.. survival of the fittest will be replaced by mutual respect and cooperation. I by no means propose to have all the answers, far from it, but I do trust that there are no problems without solutions and that as we continue to evolve, the path will become ever clearer. Ultimately fruitarianism proposes a "Live and let live" solution.
What I don't believe should be part of fruitarianism, is calorie counting, focusing on carbohydrates, electrolytes, minerals, vitamins etc etc.. I think these factors ultimately stem from "FEAR", and a clear lack of trust and faith in fruit. Most people are truly hoodwinked into following this pseudoscience side of eating, and although they themselves have no real idea what proteins or calories really are, they still wield the terms as if they were personally very familiar with them. Lying to themselves and others in doing so.
Fruitarianism is about letting go of such fears, trusting in the goodness of fruit, living as simply as one can, having faith, (there's always room for improvement!) eating when hungry, drinking when thirsty, resting and sleeping when tired. It is not about following fashion based on greed and consumerism, but about walking barefoot to regain contact with the earth, being naked, weather permitting, whenever one can do so without victimization, letting ones hair and beard, when applicable, grow naturally, not defacing ones body with tattoos, piercing, make up and chemical cleaners, certainly not undergoing pointless surgery. Rather it concerns the understanding that the medical industry is a multi billion dollar business that ultimately does NOT have our best interests at heart. Understanding that the body will heal itself from pretty much anything if we follow the rules of simplicity and fruit eating.
I believe it is also about getting closer to nature, about getting our hands covered in soil as we plant and care for new fruit trees. Not competitiveness, not Alpha-male centred and dominated society, but mutual support and understanding of one another, and using our energy toward the ultimate vision of Eden and personal spiritual growth.
Fruit has not only the ability to cleanse us both internally physically and mentally, but also applied externally is great for washing our bodies, as well as making us more spiritually aware.
As always, I feel I have barely scratched the surface, and the final peace and tranquillity that will reign will be beyond all our expectations.
