The End of Nature


Long, long ago, in scorching-hot 1988, Bill McKibben was busy writing The End of Nature, a book that cranked up the global warming warning sirens.  It was the first climate change book written for non-scientists, and it was a smash hit.  It makes an eloquent effort to convince those entranced by the dominant culture to radically change their thinking and lifestyles, this week if possible, because the biosphere is more damaged than we think.  It’s about living with great care, fully present in reality, and pursuing the healing sanity of voluntary self-restraint.

The root issue is that human cleverness has succeeded in creating so many brilliant ideas that we’re blindsiding nature.  This does not mean we’re eliminating all life on Earth.  It means that humankind has spawned powerful cultures that no longer blend in smoothly with the rest of the family of life.  The biosphere can no longer run on autopilot, because humans are fooling around in the control room and, despite good intentions, are piling up an impressive collection of devastating misjudgments.

If we look at the world of 500 years ago, we can observe a number of blotches resulting from human activities, but the atmosphere remained fairly close to its original condition, as did the oceans, and much of the planet’s land surface.  The seas were loaded with fish, and millions of bison thundered across North America.  Overall, the world largely remained the domain of Big Mama Nature.  It was able to shake off the punches from human activities.

In the last 200 years or so, this has changed.  Human cleverness is now capable of causing disturbances that are global in scale.  These include DDT, ozone holes, radiation, acid rain, and an unstable climate.  The dominant culture is discharging pollutants that affect the biosphere everywhere.  Humankind has (temporarily) forced nature out of the pilot’s seat.  This is what is meant by “the end of nature.”  Legions of radicalized consumers are now vigorously rocking the boat, to a degree that exceeds nature’s ability to compensate and maintain balance.

In recent decades, our techno-juggernaut has invented a new and improved way of suppressing nature, genetic engineering.  This represents an enormous advance in our mistake-making talents.  By fooling around with gene splicing, we are beginning to interfere with evolution’s autopilot.  Highly specialized mistake makers have pushed us beyond the amateur level of mere biosphere destroyers.  They now strive to control the future of the family of life, by fooling around with matters that were once the sole domain of the Creator.  What could possibly go wrong?

Genetic engineering gave McKibben intense nightmares.  It’s a technology with fabulous potential for creating multitudes of unintended consequences; bizarre surprises that the mad scientists could have never imagined.  Some manmade organisms might survive for millions of years, affecting the biosphere longer than nuclear waste.  Obviously, GMOs are absolutely unnecessary for our long and challenging return to balance with nature.

McKibben is a good thinker, a good writer, and a good-hearted human being.  He’s an environmental wordsmith who is also a Christian, providing a perspective that is not common in green literature.  The end of nature deeply offended his beliefs.  Many Christians don’t get much farther than the instructions to “multiply and subdue,” which imply that God made the world for us to dominate and exploit.  McKibben knew that the scriptures could be annoyingly inconsistent.  He was fond of the Book of Job, which teaches that humans are not the center of the universe, and wilderness is not ours to trash.

As the dominant culture furiously thrashes the planet, glaring questions arise — why doesn’t God stop us?  Did he die, or move away?  McKibben sidesteps the sixth chapter of Genesis, where God realized that creating humans was a huge mistake, because they turned out to be remarkably wicked.  God corrected his blooper by bringing “a flood of waters upon the earth, to destroy all flesh, wherein is the breath of life, from under heaven; and every thing that is in the earth shall die.”  Today, humans are the ones executing the end of nature, not the Creator.  No other species is so clever — or so willing to mindlessly imitate a pissed-off sky god.

The End of Nature is also notable because it does not reek with a pungent anthropocentric stink.  The path to healing requires the abandonment of human superiority, a deadly brain fever.  McKibben concurs with Dave Foreman, “Each of you is an animal, and you should be proud of it.”  It’s not easy for us to accept that we are delicious two-legged meatballs wandering around in the food chain, and that the rest of creation is at least as important as we are.

Green wordsmiths rarely reveal a profound love for the natural world, maybe because it’s unprofessional, or because they have no spiritual connection to life, the norm in this society.  The focus for many green thinkers is finding a way to maintain our “high standard of living” while leaving no scars on the ecosystem, an absurd and impossible quest.  Usually, their primary objective is generating enough electricity to keep their gizmos glowing and humming.  Food is lower on the list, and population reduction is nowhere to be seen.

Lately, hysterical electricity addicts have been hallucinating that nuclear energy is the silver bullet solution.  McKibben noted that if we quit burning fossil fuels to generate electricity, and switched to nuclear, our carbon dioxide emissions would only drop 30 percent, because much of our economy cannot run on electricity (ships, planes, trucks, trains, etc.).  Furthermore, carbon dioxide is only half of the greenhouse gases we are releasing.  Alas, there is no free nuclear lunch.

McKibben loved nature.  While writing, he lived in the Adirondacks, and he gushed with adoration for the surrounding forest and mountains.  Outdoors, he felt the presence of God far more than when he sat indoors among a congregation of holy rollers.  God created nature, not cities.  One of God’s great delights was annihilating cities, according to the scriptures.

McKibben confessed that he’s also an American who enjoys the cool things that modern living provides, and he has no desire to live in an unheated cabin.  Modern living is so comfortable.  Unfortunately, it’s beating the stuffing out of nature.  There is a vast chasm between the way of life we enjoy, and a sustainable life.  If we were rational, we would leap into “an all-out race to do with less.”  Instead, we desperately cling to a blind faith in technological miracles that will magically eliminate all need for living intelligently.

A memorable portion of the book describes the author’s sincere struggle to find answers, tirelessly wrestling with hordes of demons and inconvenient truths.  He tries so hard to find workable approaches, but there are no quick and easy solutions.  Centuries will pass before balance returns.  But our biggest obstacles are psychological, and radical change is not impossible, in theory.

The nations of the world actually cooperated in sharply reducing the use of DDT, and ozone-eating CFCs, because the risks clearly exceeded the costs.  Fossil energy is different.  Billions of people literally cannot survive without oil.  Therefore, the radical changes we need will not happen anytime soon, if ever.  We can continue living like there’s no tomorrow, or we can make a heroic effort to encourage a gentler collapse — McKibben’s preference.

To recharge his sanity, he enjoys stepping outdoors at night, and gazing at the stars.  The rest of the universe is still as wild and free as it ever was.  What could be more inspiring?

Too Hot to Touch


Modern society provides a long menu of predicaments to inspire our nightmares.  For a number of years, climate change has been hogging the spotlight.  It’s time to have more nightmares about radiation.  Folks think that if we simply quit building new reactors, the nuclear boo-boo will go away, and we can forget about it — wrong!  William and Rosemarie Alley have shed much light on the subject with their book, Too Hot to Touch.  It reveals a deeply embarrassing chapter that has been omitted from the glorious epic of technology and progress.

Nuclear weapons were invented during World War II.  Nagasaki and Hiroshima were turned into ashtrays, but the enormous unintended consequences of half-baked genius have dwarfed the destruction of two cities.  We continue to create stuff that will remain extremely toxic for millions of years, and none of it is stored in secure permanent facilities, where it will cause no harm.

The war was followed by an arms race.  A hundred new bombs were detonated at the Nevada Test Range between 1951 and 1962.  Nuke tests became a tourist attraction.  Families sat in folding chairs at open-air spectator sites to see the amazing mushroom clouds.  A few minutes after the blast, they were sprinkled with fine dust.  Several decades later, the region became “the thyroid cancer capital of the world.”

Lunatics became giddy with nuclear mania.  Some wanted to blast a new canal across Panama.  Others dreamed of a coast-to-coast waterway across the U.S.  Others wanted to nuke Gibraltar, and turn the Mediterranean into a freshwater sea.  In the Soviet Union, 120 bombs were used for earthmoving projects.

In 1954, construction began on the first U.S. nuclear power reactor at Shippingport, Pennsylvania.  At that time, nuclear waste was not seen to be especially dangerous.  Robert Oppenheimer, at the Atomic Energy Commission, referred to the issue of radioactive waste as “unimportant.”  Experts were possessed by a stupefying blind faith in scientific magic — there is a brilliant solution for everything!

They contemplated a variety of schemes for making high-level waste disappear.  Some recommended shooting it into space, or burying it in sea floor clay beds.  The Soviets disposed it via deep well injection, in a liquid form that may not sit still for millions of years.  The U.S., U.K., France, and the U.S.S.R. have dumped a lot of waste in the oceans.  The Irish have caught contaminated lobsters and fish.

There are a number of radioactive elements and isotopes.  All of them are unstable and become less dangerous over time, degrading at varying rates of speed.  Most forms of uranium are mildly radioactive.  The atoms that are heavier than natural uranium are manmade, and some remain dangerous for millions of years.  Some are water soluble and highly mobile.  Some are picked up by plants and animals, and are biomagnified as they move up the food chain.

Experts eventually realized that high-level radioactive wastes were nastier than expected.  They had to be stored underground, in geologic repositories that would remain stable for a million years.  Serious research began at an old salt mine in Kansas.  Then, a plutonium plant in Colorado burned, and high-level waste was shipped to Idaho, where cardboard boxes of it were dumped into open trenches.  The media reported the story, and the nation soon realized that nutjobs were in charge of handling terrifically toxic dreck.  This detonated high-level fear.  Kansas promptly nuked the proposed repository.

The next hot prospect was Yucca Mountain, on the edge of the Nevada Test Site.  The government invested $10 billion on 25 years of research.  The objective was to prove that the site would be safe for a million years.  No place on Earth would be a perfect site.  Dr. Alley believed that Yucca Mountain was close enough to ideal.  (He spent years on the project, working for the U.S. Geological Survey.)

The core problem was that there were no politically suitable sites in the entire U.S., because every state would fiercely oppose a repository within their borders.  The public had a reasonable fear of high-level waste.  They also had a reasonable lack of trust in anything the government told them, after years of lies and deceptions.  Nevada was no exception.  The government’s nuclear testing had already turned much of the state into a radioactive wasteland.

Obama was elected in 2008.  Steven Chu was his Secretary of Energy.  In March 2009, Chu announced, “Yucca Mountain was not an option.”  He presented no explanations or alternatives.  Why did Chu kill the project?  “Virtually all observers attributed the decision to pull the plug on Yucca Mountain as political payoff to Senate Majority Leader Harry Reid, a Democrat from Nevada.  Nevada was a swing state in the election, and Obama had pledged to kill Yucca Mountain, if elected.”

So today, “there are some 440 nuclear power plants in 31 countries.  More are on the way.  Yet, no country on Earth has an operating high-level waste disposal facility.”  As of 2012, American taxpayers were responsible for storing a growing collection of high-level waste — 70,000 tons of spent fuel, and 20,000 canisters of military waste.  It’s being stored at 121 sites in 39 states.  In 15 other nations, 60 nuclear reactors are being built.

Industrial civilization is doing a fabulous job of trashing the planet’s atmosphere, forests, soils, oceans, aquifers, and biodiversity.  This is simply business as usual, and most of humankind is staring at their cell phones.  The future doesn’t matter — with the exception of nuclear waste repositories.  Almost no study has been devoted to the risks of doing nothing, and letting the crap remain where it is forever.  The Alleys steer around this red-hot issue, leaving readers to conjure worst-case nightmares.

Let’s take a side trip to Google.  The average U.S. reactor is 32 years old.  Reactors are licensed for 40 years.  When a license is not renewed, the reactor must be decommissioned, a process that often takes 60 years.  First, the reactor is turned off, and the fuel rods removed.  Then, wait 50 years.  This allows the radiation levels in the facility to cool off, making it much safer for the remaining work to proceed.  The buildings and contaminated soils are removed, and the site is restored to a harmless field.

Fuel rods have a working life of about six years.  Then, the spent fuel, which is still highly radioactive, is moved to cooling pools, where it must remain for at least five years.  Then, ideally, it is stored in dry casks.  If the pumps for the cooling pool quit, the water boils, the pool evaporates, and the rods are exposed to air.  If the uranium pellets in the rods are exposed to air, they melt, and begin releasing radioactive gasses. 

The meltdowns at Three Mile Island, Chernobyl, and Fukushima were triggered by overheated fuel rods.  Cleanup efforts at Chernobyl are hampered by the Ukraine’s wheezing economy.  Around Chernobyl, citizens were permanently evacuated from a Zone of Alienation, which is larger than the state of Rhode Island.

In the U.S., the planned geologic repository did not materialize by the promised date, and no site has been approved, so spent fuel is piling up at reactor sites.  The Alleys note that some U.S. pools have been loaded with four times more rods than they were designed for, which increases potential risks.  Moving the rods to safer dry casks would cost billions of dollars.

Are we feeling lucky?  What will the world look like in 50 years?  Will effective geologic repositories be built in time?  Fifty years from now, will we have the oil, heavy equipment, transportation systems, functional governments, work crews, and wisdom to safely decommission the existing 440 reactors, plus the new ones being planned?  Will all of the reactors safely avoid disasters resulting from earthquakes, volcanoes, plane crashes, warfare, equipment failures, human errors, and sabotage?

If we cared about the generations to come, and if we were rational, what would a sane plan look like?  Today, orbiting spacecraft passing in the night can clearly see the city lights below.  My grandparents, and all of their ancestors, were born in homes without electricity.  They managed to survive without light bulbs, TVs, cell phones, or the internet.  They were good people who had satisfying lives.  The lights cannot stay on forever.
