The problem I see in your views is that overpopulation is a source of scarcity, misery, environmental damages, conflicts and wars.
That's true, I mean back before the rise of modern societies, one was able to reproduce so much because there existed a natural balance between birth rate and death rate before the age of procreation. So there always was a "just enough" quota of living beings (in this case, humans) inside an ecosystem.
Nowadays, thanks to scientific advancement and the suppression of all natural predator to man (except certain epidemic diseases, which most likely work as a way to regulate the global population naturally. It's the case for some animals such as deers or rabbits, who die of epidemic diseases because their natural predators have been removed) people are now able to enjoy the company of many children of their own, who will live on to produce countless offspring themselves.
This, of course, is completely out of balance with the natural order of Life, and thus Life must find a way to return to a viable situation, or else the entire system will be compromised. Just like that time where those O2 producing bacteria threatened the whole of existence on this planet.
Life has many ways to deal with such problems, may it be "exterior" to the antagonist, such as natural disasters, climate change, diseases etc... or within the antagonist: sudden collective desire for war, conscious or unconscious biocidal actions/creations (GMO's, pesticides, vaccines, you know the drill).
As for the latter, I think very few people are "conscious" of the damage they make, most are just unconsciously blind to the final outcome. My cousin started her biology studies so she can one day make "superfoods" (GMO's), but I'm pretty sure she'll be -or already is- in denial of all that's wrong with them. I haven't discussed it with her, so I don't know her stand on the matter.
However, us who do our possible, and have the knowledge and skills to avoid the bad stuff, we might indeed be the future inheritors of this planet. How I see things right now, the GMO/pesticide/vaccin/weapon companies and communities are the necessary Shiva of this earth. The destructive (cleaning, I might dare) forces of life. Then there's the ignorant, the people who are not intuitively driven to their own salvation. They consume what is sold to them and happily do so. Both them, and probably the Shiva minds, will someday disappear, as the result of their own, unconscious actions, way of life.
It is no coincidence that you where one day brought to this diet, this lifestyle. Intuitively you where brought to it, destiny brought you to it. I feel you and I, we are the souls that will inherit this earth in the end.
No one is wrong in their path, I must note. Shiva, Insensible, Clear Minded.
Maybe it sounds crazy, extreme, maybe I'll change my mind on this, but this is how I feel things are being played right now.
Some clearing up and additional details about the idea I posted:I feel there's some clearing-up to be done about my idea.
I think it was wrong to split people into three definite groups (Shiva, Insensible, Clear-minded).
It may seem as if I was saying: "from this day on, every paleo dieter will live on to be heir of this planet. And all other, be it the naive sheep waiting to get slaughtered, or the evil wolf who's only purpose is to murder in mass, will unconsciously commit suicide. And it will all happen in the next 50 years, max".
I'm aware Life is not that black and white. It's much more colorful than that. Life is not static, absolute: it is moving, fluid, constantly changing. Every living being have a purpose.
The shift will be gradual. Perhaps centuries long.
Some Shiva might become aware of the direction they're taking and turn to a healthier lifestyle.
Some "ignorant" people today may later give birth to enlightened individuals.
Some enlightened may turn back to their old ways, or on the contrary turn knowledgeable some ignorants, in a conscious way or not.
The list of possibilities, associations, is endless.
All this will eventually lead to renewed balance.
