The U.S. state of Georgia has something of a personal Stonehenge. And, while I’ve never been to Georgia—and, really, I’ve never been inclined to go—I think I can assume that these stones are a bit… heterodox… for their place below the Mason–Dixie line.

When I think of large tablets being erected in some southern state, I imagine a marble copy of the 10 Commandments making an awkward addition to a courthouse or State Capitol. But the Georgia Guidestones, nestled in the earth in the state’s Elbert County, are anything but religious strictures. They are, rather, suggestions and “guidelines” on how humanity can conduct its affairs on this planet, rather than please a celestial being beyond the Earth. Having derided the Guidestones as artifacts of the “New World Order,” tinfoil-hatted conspiracy theorists have desecrated them a number of times now. But the message of the Guidestones still stands strong. It reads:

Maintain humanity under 500,000,000 in perpetual balance with nature. Guide reproduction wisely — improving fitness and diversity. Unite humanity with a living new language. Rule passion — faith — tradition — and all things with tempered reason. Protect people and nations with fair laws and just courts. Let all nations rule internally resolving external disputes in a world court. Avoid petty laws and useless officials. Balance personal rights with social duties. Prize truth — beauty — love — seeking harmony with the infinite. Be not a cancer on the earth — Leave room for nature — Leave room for nature.

I can pretty much agree with all of this. But the most important guidelines, I would say—especially considering humanity’s current predicament on a fragile planet of finite resources—have to be 1, 2, 9, and 10. Let’s look at the current state of world affairs, and dissect the importance of the first and last two guidelines:

1. “Maintain humanity under 500,000,000 in perpetual balance with nature.”

Current population levels, clocking in at about 7.2 billion (as of 2015), are wildly unsustainable. We have committed ourselves to serious overshoot. With this many people on the planet, and the population expected to rise to between 9-11 billion by the end of the century (if our species can even make it that far without wiping itself out, and much of the Earth’s biodiversity with it!), we are barreling toward catastrophe. Couple this with climate change, environmental degradation, resource depletion, and pollution, and it becomes clear that we are leaving ourselves, and our decedents (if they even manage to survive), a hell on earth. I don’t think that 500,000,000 needs to be a strict number which we should follow, but in general we should aspire to have a much lower number of humans living on the planet. This would free up a huge amount of resources for both humans and other lifeforms to reap and share. When we look at the dramatic loss of fresh water, as well as mineral depletion and the fast-approaching “peak everything,” it becomes clear that this is a better course of action. The loss of half the world’s wildlife should serve as a wake-up call.

2. “Guide reproduction wisely — improving fitness and diversity.”

I will say that I’m not to keen on the “fitness and diversity” bit. (It sort of smacks of eugenics.) But, in any case, we most certainly should guide our reproduction wisely. To begin with, isn’t it morally questionable to bring a child into a world whose future looks as grim as ours? Secondly, if we do bring children into this world, why are we bringing so many of them into nations where poverty, war, instability, and food and water scarcity run rampant? The explosive population growth of developing countries shows that many parents are not considering their children’s futures, nor the future of the planet. It doesn’t take much brain power to realize that, on a planet quickly entering the opposite of an ice age, and one of finite resources, having a bunch of kids is not only bad for oneself and one’s country, but for society, the world’s ecosystems, and the future as a whole. People should consider where and when they have children, and how many they are going to have. Granted, many pregnancies are unwanted, and a lack of access to birth control thus imperils many societies. Sadly, for cultural and religious reasons, many countries still ban contraception. My contention is that they only do so to the detriment of their own national stability.

9. “Prize truth — beauty — love — seeking harmony with the infinite.”

Before you pass this off as some cliché hippie platitude, I would suggest that you take into account the fine points of this statement. The operative phrases in this passage—”truth,” “beauty,” “love,” “harmony,” and “infinite”—are some of the most important aspects of the human experience, and well represent the goals and aspirations of many people the world over! The personal and spiritual achievement of self-actualization (though implicitly indescribable), could be very well expressed using these phrases. And what does this world need more, if not a change of heart—a collective heart that embraces opportunity, infinity, harmony, and love—that leads to prosperity for all living beings? As comedian Russell Brand has stated, “The fusion of spirituality and activism feels like it is emerging for the first time since the Sixties.” I hope he’s right.

10. “Be not a cancer on the earth — Leave room for nature — Leave room for nature.”

We seem to be doing a terrible job on this last one. All of the aforementioned issues add up to this: humans are currently a disease to the biosphere. In our current predicament it seems that humanity, and the biodiversity of the planet, will be destroyed by selfishness, greed, and ignorance. (Buddha was on to something!) Perhaps we would like to save ourselves, our children, and future generations from the calamity of climate change and ecological destruction? We must dramatically change course if we want that better future, and, as of right now, it has been decided that extra yachts are more important.

We can change our practices and policies in order to live more harmoniously with the Earth’s ecosystems, thus ensuring not only the survival of many plant and animals species, but also our own.
