Thanks for Not Breeding

“Man in his misguidance has powerfully interfered with nature. He has devastated the forests, and thereby even changed the atmospheric conditions and the climate. Some species of plants and animals have become entirely extinct through man, although they were essential in the economy of Nature. Everywhere the purity of the air is affected by smoke and the like, and the rivers are defiled. These and other things are serious encroachments upon Nature, which men nowadays entirely overlook but which are of the greatest importance, and at once show their evil effect not only upon plants but upon animals as well, the latter not having the endurance and power of resistance of man.” 1832

Johann Wolfgang von Goethe (1749-1832)

Q: Is parenthood bad for Earth’s ecology?

“Motherhood is a proud profession” the wise old bumper sticker says. Hard to argue with that, except to include both genders. Parenthood is one of the most critical and yet undervalued endeavors we can undertake today.

Many VHEMT Volunteers and Supporters are parents, having achieved awareness after making their heirs. And many who haven’t bred are more lucky than righteous. The past is history. What really matters is the number of off-spring we don’t create in the future.

Complaints of mothers and fathers being disrespected by others who care about planet Earth aren’t entirely imaginary. A kick-butt mentality dominates our society: identify the enemy and kick its butt. Because breeding is the heaviest impact we can have on Nature, some see parents as enemies of the planet. But, if we all hop around in circles trying to kick each other’s butts, all we’ll get is pratfalls. We don’t have to be brain surgeons to figure out that kicking butts isn’t the way to change minds.

Plenty of young people could benefit from some responsible parenting. Those of us who are so inclined may rightly be proud of accepting the challenge and responsibility of parenting an existing child.

The work of preserving and restoring what’s left of Earth’s biosphere won’t be finished in our lifetimes, so it’s critical that we include younger people, giving them the opportunity to carry on the work. However, creating more of us to carry on is unnecessary and counter-productive.

Q: What’s the big deal about animals going extinct?

Some folks say, “Extinction is natural. 99.9% of all species of plants and animals that have ever existed have gone extinct.”

Puts it into perspective, doesn’t it? We shouldn’t get peeved about a few million extinctions today. It’s all part of the natural process of life on Earth.

By the same reasoning, we shouldn’t care about people dying young. Most people who have ever lived are already dead, and all of us will die eventually. It follows that extinction of the human race shouldn’t raise an eyebrow, either.

However, if it’s true that species alive today represent only 0.1% of Earth’s entire biological history, their extinctions are all the more tragic. After evolving at the expense of kabillions of other species, and passing genetic coding on through billions of years, any species alive today, including our own, deserves profound respect and reverence.

In a sense, all living things are at the peak of evolution. Sacrificing the very existence of any life form for something as superfluous and transitory as money is an outrageous crime against Nature.

Today’s extinction rate is estimated to be between a hundred and one thousand times the average for the eons, and virtually every species’ demise stems from the activities of one species. Guess who.

Our voluntary extinction for the eternal good of all other life on Earth will be the ultimate demonstration of the best qualities of humanity: compassion and reason.

True words, no matter who wrote them.

Q: Are humans the most important species on Earth?

We certainly have the most power. We have the power to destroy the planet or to help it return to a natural paradise. Our choices have more impact than the choices of other animals, so in some ways, Homo sapiens is the most important species on Earth.

Another test of our importance is to ask how well Earth’s biosphere would get along without us. The higher a species is on the food chain, the less important it seems to be to the survival of that chain.

Biodiversity is being greatly diminished by the extinction of carnivorous predators, and their prey species are affected adversely, but the chain is being shortened more than it is being broken. Likewise, humans have virtually left the food chain and will not create a missing link when going extinct.

Microscopic bacteria in the intestines of termites is critical to the continuity and survival of Earth’s web of life. As special as Homo sapiens may be, we seem to be an expendable species in this biosphere.

Extinction of the couple dozen species which live only on humans is tragic, but unavoidable. Although our hearts might not go out to the crab louse, and few of us have ever seen any of the billions of mites and microbes which live on and in us, each is a unique lifeform contributing to the diversity of life on Earth.

Q: Don’t humans have a place in Nature?

It has been said that our environmental woes stem from being out of touch with the natural world. Perhaps this check list will help to restore our sense of place in Nature. Join the search for a human niche, and help determine where on Earth we fit.

Check off as many niches as fit us:

  • Evolution’s crowning achievement
  • Most advanced being on Earth
  • Integral part of the web of life
  • Exotic invader
  • Parasitic pest
  • Dominator, usurper of resources
  • Fluke of evolution, apart from nature
  • Spiritual unifier of heaven & earth – of divinity and Nature
  • Worshipper of Nature as god/goddess
  • Transcender of physical realm
  • Steward, caretaker of lesser species
  • Equal with all life forms
  • Link on the food chain
  • Restorer of balance, undoer of civilization
  • Defender of Nature
  • Cancer or virus
  • Soon-to-be-extinct altruist
  • Other

Many cling to the quaint notion that we are still a part of Nature, and perhaps we are, depending on how “a part of” is defined.

An established and balanced ecosystem functions in a dynamic symbiosis. All species interact with each other in three possible ways: mutualistic, communalistic, or parasitic. A mutualistic relationship helps both organisms. A communalistic relationship neither helps nor harms the interacting organisms. A parasitic relationship helps one and harms the other.

Are we a part of Nature in the same way a timber company is a part of the forest? Or the same way a farmer is part of the farm? We could be part of nature the same way, say, an otter is: eating sea urchins and being eaten by sharks.

We were once like the otter, part of the ecosystem. Then we developed agriculture, and have become parasitic, depending on exploitation of Nature for our survival, but giving nothing back.

The fossil record shows that each time Homo sapiens entered a continent, a spasm of extinctions followed. Exotic invaders typically disrupt ecosystems, and we are no exception.

On some philosophical level there is no doubt some truth feeding the myth. However, by examining our daily lives, and asking ourselves, “What part of my normal day is a part of Nature?” the sad truth is revealed.

Q: Isn’t over-population just a human distribution problem?

It’s true that people are crowded together in some areas while other areas remain relatively uninhabited, but let’s define inhabited. Just because we don’t see houses and people doesn’t mean the land is uninhabited.

Farm land and range land is inhabited, as are military bases and bombing ranges. Second growth forests are actually managed tree farms for human benefit, many are over-grazed as well. If we define uninhabited as areas where human influence is ecologically insignificant, we’ll find very little land left to spread out on.

It’s naïve to think that all we have to do is distribute ourselves better to solve crowding problems. We need far more than a place to squat. We need water, food, and warmth. And, whether we realize it or not, we need large wilderness areas, uninhabited by human beings.

In terms of environmental impact, crowding humans together in cities preserves natural areas better than spreading us evenly over the whole land. This, like all migration-control attempts, provides only a temporary reprieve. Population centers send out their tentacles to bring in supplies from rural and natural areas.

A more accurate analysis of our impact is what William Rees of British Columbia, Canada calls our “ecological footprint.” To roughly calculate your ecological footprint, take this simple quiz.

Consumption has a lot to do with our footprints, and reproduction multiplies consumption. After determining the size of your footprint, add 50% of it for each new person you have created. Do not count adopted, foster, or step children.

When our population density improves, we won’t have to convert natural ecosystems into agriculture, industry, housing, and amusement farms.

Viewing Earth at night reveals the extent of human habitation. (North Koreans turn their lights out at night).

National footprints have been calculated by the Global Footprint Network, which determine whether a nation’s footprint is smaller than biological capacity—providing an ecological reserve—or is in overshoot and has an ecological deficit.

Earth’s carrying capacity for our species was exceeded in the 1970s and our overshoot increases as population and consumption increases. At the same time, carrying capacity is reduced by topsoil loss, desertification, cropland salinization, collapse of fish stocks, depletion of aquifers and other fresh water sources, and so on. In 2010, we used one and a half year’s worth of Earth’s resources: an estimated overshoot of 50%.

Q: Won’t Mother Nature restore a balance if we get too over-populated?

“It is a simple logical truth that, short of mass emigration into space, with rockets taking off at the rate of several million per second, uncontrolled birth-rates are bound to lead to horribly increased death-rates. It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for ‘natural’ methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.”

~Richard Dawkins, The Selfish Gene

When the Dutch explorer Jacob Roggeveen discovered Rapanui on Easter day 1722, there were about 2,000 people, no trees or bushes over ten feet high. No bats, birds, lizards, or land snails. They did have chickens, their only domestic animal. Their boats were so leaky that they had to bail as much as paddle. It was not always this bad on the island.

Pollen analysis of core samples taken back to England for study, and analysis of kitchen middens, is revealing a drama which is being played out on a global scale. Just as we can’t leave Earth, they couldn’t leave Rapanui.

Around 400 CE, a few Polynesians landed on a tropical paradise. Within a century they were constructing the familiar stone statues which Erich Von Daniken figured must have been carved by visitors from space—the people sure couldn’t have done it with their lack of materials.

For at least 30,000 years before the arrival of this new exotic invader, Rapanui was a thriving, diverse ecosystem. Huge palm trees were perfect for canoes, which they used to hunt porpoises. By 800, destruction of the forests was well underway, and by 1400 the palm was extinct. Human population may have peaked at 20,000.

Imagine the last tree being cut for a canoe and some radical environmentalist spouting doom and gloom about there being no canoes for future generations. Porpoise was about one third their diet, and couldn’t be hunted without the large canoes. Trees were also used to move the statues from quarries, as each clan worked to get ahead.

It appears that society broke down quickly, with tools in the quarries abandoned and statues half-finished. The picture is still being filled in, and debate continues regarding cannibalism. A Rapanui insult from modern times translates as “Your grandmother’s flesh sticks in my teeth.”
Q: Why extinction? Why not just get our population down to a sustainable size?

VHEMT Supporters favor this goal, while Volunteers see extinction as the only sure way to avoid breeding ourselves back to today’s density.

Homo sapiens’ population was reduced to fewer than 10,000 individuals at some time in our existence, an estimate based on the similarities of our DNA. This bottleneck likely happened 73,000 years ago when the Toba volcano rained ash on our habitat and precipitated a volcanic winter. Ten thousand would certainly be a sustainable number, if we weren’t so fecund clever.

Introduction of one breeding pair of an exotic species is all it takes to disrupt an ecosystem and cause extinctions of native species. We have evolved into a virtual exotic invader of Earth’s biosphere as a whole, incompatible with undomesticated life forms.

If we use a balance scale like blind Justice holds, place all the species going extinct on one side, and place us on the other—giving us about a 100,000 times more weight because we invented the scales—the sales will tip in favor of our extinction, even with our weighted advantage.

If Justice uses her sword to mete out vasectomies when the verdict is revealed, let’s hope she takes off the blindfold.

Perhaps by considering our own extinction, we will more fully appreciate what the extinction of other species means. Big thicket hog-nosed skunks and rabbit-eared tree rats may be difficult for us to identify with, but then, so are some people’s in-laws.

“Darwin’s dice have rolled badly for Earth. It was a misfortune for the living world in particular, many scientists believe, that a carnivorous primate and not some more benign form of animal made the breakthrough.”

Q: Won’t another species come along and do the same thing after we’re gone?

It isn’t impossible that another species will come along and do as we are, just highly unlikely. No species, as far as we know, has ever taken the evolutionary sidetrack we have. However, the super-predator theory suggests that evolution occasionally produces predators so efficient that they wipe out their food supply and naturally go extinct themselves. Their existence is so short that evidence in the fossil record is weak.

A similar scenario offers a possible solution to the Fermi Paradox. Perhaps evolution selects against our type of intelligence: clever beings wipe themselves out in a relatively short time. “Let’s put these together and see what happens.”

Many species, not just apes, exhibit intelligence on a par with us—though we try to skew the criteria for intelligence to make it seem like we’re the smartest. None of them seem to be in line to convert the rest of the world into their habitat as we are doing.

We have an opportunity to prove we can behave benignly despite our biological heritage. We may never be able to stop fighting with each other, exploiting the natural world, or giving in to other primal urges, but we can stop breeding and eventually our nature will be history.
