THIRTY YEARS AGO, in between my sophomore and junior years of college, I was
diagnosed with bladder cancer. Those are amazing words to write: Thirty years
ago I had cancer. I had just turned twenty. I was hoping that I would live
long enough to have sex with someone; I hadn’t done that yet. I could not have
imagined, while lying in my hospital bed, exhaling anesthesia, that someday I
could write, Thirty years ago I had cancer.
Last fall, on a sunny afternoon, the phone
rang while I was trying to meet a writing deadline. It was the nurse in my
urologist’s office. She was calling to say that the pathologist had found, in
the urine collected from my last cystoscopic checkup, abnormal cell clusters.
And also blood.
After I hung up, I looked out the window of my
small house where the sun still shone on the last of the marigolds and tomato
vines. I looked down at my computer screen where the cursor still blinked on the
same paragraph. I could hear in the kitchen the tomatoes still bobbing around in
the stockpot that was steaming away on the stove. The world was still the same,
but it felt to me a suddenly altered place.
I provided a second
urine sample for further testing, and based on the results of that, a third
sample that was sent out for genetic analysis. Ten days later, I got a call from
the urology nurse. The results were normal.
So what am I trying to
say here? Am I fine or not fine? Well, I don’t know. I’m living within that
period of time known as watchful waiting. Much of my adult life has been one of
watchful waiting.
Watchful means vigilance, screening
tests, imaging, blood work, self-advocacy, second opinions, and hours logged in
hospital parking garages. Waiting means you go back to your half-finished
essay, to the tomatoes on the stove. You lay plans and carry on within the
confines of ambiguity. You meet deadlines and make grocery lists. And sometimes
you jump when the phone rings on a sunny afternoon.
Thirty years
ago I had cancer.
After I left the hospital, I went back to the
university, resumed my life as a biology major, and began mucking around in the
medical literature. It didn’t take me too long to learn that bladder cancer is
considered a quintessential environmental cancer, meaning that we have more
evidence for a link between toxic chemical exposures and bladder cancer risk
than for almost any other kind of cancer, with data going back a hundred years.
I also discovered that the identification of bladder carcinogens does not
preclude their ongoing use in commerce. Just because, through careful scientific
study, we learn that a chemical causes cancer doesn’t mean that we ban it from
the marketplace.
I also learned that, in spite of all this
evidence, the words carcinogen and environment rarely appeared in
the pamphlets on cancer in my doctors’ offices and waiting rooms. Nor were these
words used much in conversations I had with my various health-care providers,
who were interested instead in my family medical history. I was happy enough to
provide it. There is a lot of cancer in my family. My mother was diagnosed with
breast cancer at age forty-four. I have uncles with colon cancer, prostate
cancer, stromal cancer. My aunt died of the same kind of bladder
cancer—transitional cell carcinoma—that I had.
But here’s the punch
line to my family story: I am adopted. I’m not related to my family by
chromosomes. So I began to ask hard questions about the presumption that what
runs in families must necessarily run in genes. I began to ask, what else do
families have in common? Such as, say, drinking water wells. And when I looked
at the literature on cancer among adult adoptees, I learned that, in fact, the
chance of an adopted person dying of cancer is closely related to whether or not
her adoptive parents had died of cancer and far less related to whether or not
her biological parents had met such a fate. But you would never know that based
on the questions asked on medical intake forms.
So thirty years
ago, as a college undergraduate, I made a bet. I bet that my cancer diagnosis
had something to do with the environment in which I lived as a child. And I
think I was right about this.
As I learned years later, while
researching my book Living Downstream, the county where I grew up, along
the east bluff of the Illinois River, has statistically elevated cancer rates.
Three dozen different industries line the river valley there, and farmers
practice chemically intensive agriculture along its floodplains. Hazardous waste
is imported from as far away as New Jersey, and the drinking water wells contain
traces of both farm chemicals and industrial chemicals, including those with
demonstrable links to . . . bladder cancer.
TWENTY YEARS AGO, in
the fall of 1988, when I was a graduate student in biology at the University of
Michigan, I made another bet. I was working as an opinion writer at the
Michigan Daily, the student newspaper there. My editor and I laid bets as
to which system would collapse first—economy or ecology. I said ecology. I think
I was wrong.
I think we were both wrong. They seem to be crumbling
simultaneously.
Let’s compare our twin “eco” systems. Our economy
and our ecology have in common, it seems to me, a number of shared attributes.
Both are complex, globalized systems whose interconnections are little
understood until something goes wrong. Who knew that mortgages in California
could lead to bankruptcy in Iceland? But there it is. Who knew that the miracle
of pollination depends on the synchronicity of time and temperature? But the
ongoing decoupling of day length—which awakens the flowers—from ambient
temperature—which awakens the bees—reveals that it is so dependent.
In both systems, eroding diversity creates fragility, as when
financial systems merge and collapse, as when farming systems become
monocultures and thereby vulnerable to catastrophic pest outbreaks. Damage to
both systems is made worse by positive feedback loops. In the economic world,
panic and fear drive investment decisions that lead to more panic and fear. In
the ecological world, greenhouse gases raise temperatures that melt permafrost.
Melted permafrost rots and releases more greenhouse gases.
Here’s
a key difference, though. For one of our failing eco-systems, we became
immediately engaged in drastic and unprecedented measures to rescue it—even
though no one seemed to understand it very well. And for our other eco-system .
. . well, it’s still widely considered too depressing and overwhelming to talk
about in much detail.
As part of my work, I visit a lot of college
campuses. Lately, I’ve been asking students to engage in a thought exercise:
Imagine that ecological metrics were as familiar to us as economic ones. Imagine
ecological equivalents to the Dow, NASDAQ, and S&P that reported to us every
day—in newspapers, on radio, on websites, on the crawl at the bottom of TV
screens, on oversized tickers in Times Square—data about the various sectors of
our ecological system and how they are faring.
What are the
atmospheric parts per million of carbon dioxide today? Has the extinction rate
become inflationary? What is the exchange rate between sea ice and fresh water?
What is the national deficit of topsoil?
Now imagine that the
mainstream media were as interested in the thoughts of the president’s
ecological team—most notably marine biologist Jane Lubchenco, who now leads the
National Oceanic and Atmospheric Administration, and climate expert John
Holdren, the president’s new science advisor—as they are in the opinions of his
economic team. Imagine if, in primetime interview after interview, these public
servants provided us regular environmental analysis. On an almost daily basis,
the American citizenry would be reminded that one in every four mammals now
appears to be heading toward extinction. The Gulf Stream, which drives nutrient
cycling in our oceans, is starting to get wobbly, while dead zones in the oceans
are growing. The oceans, we would be informed, provide half of our planetary
oxygen. Shoveling coal into ovens to generate electricity is loading the
atmosphere with mercury, which rains down and is transformed by ancient bacteria
into the powerful brain poison methylmercury.
Methylmercury is
siphoned up the food chain, concentrating as it goes, so that nearly all
freshwater lakes and streams east of the Mississippi are now unfishable, and we
must advise women and children against eating tuna salad sandwiches.
Imagine that all Americans find out, whether they want to or not,
that atmospheric loading of carbon dioxide is acidifying the ocean in ways that,
if unchecked, will drop pH to the point where calcium carbonate goes into
solution, and that will spell the end of anything with a shell—from clams and
oysters to coral reefs.
Suppose that ecological pundits discussed
every night on cable TV the ongoing disappearance of bees, bats, and other
pollinators and the possibly dire consequences for our food supply. Suppose we
received daily reports on the status of our aquifers. Suppose legislators and
citizens both agreed that if we don’t take immediate action to bail out our
ecological system, something truly terrible will happen. Our ecology will
tank.
The fact that nothing close to this is happening is the
difference between economy and ecology, both of which share an etymology:
eco, from the Greek oikos, meaning “household.”
TEN
YEARS AGO, I gave birth to a child. After twenty years as a solitary adult
ecologist, I became a habitat, an inland ocean with a marine mammal swimming
around inside of me. I became a water cycle. A food chain. A jet stream. My
daughter’s name is Faith. I’ll leave it to you to imagine why an adopted cancer
survivor might name a daughter Faith. My daughter is planning a career as a
marine biologist. She wants to write her first book on the octopus. My son
Elijah is seven. He is named for the abolitionist Elijah Lovejoy, who hails from
my home state of Illinois. Elijah wishes to be the president, a farmer, or a
member of the Beatles. He figures there are two job openings there
already.
Since becoming a mother, I’ve made another bet. I am
betting that, in between my own adult life and my children’s, an environmental
human rights movement will arise. It’s one whose seeds have already been sown,
and it’s one with a dual focus. First, the environmental human rights movement
will take up with urgency the task of rescuing and repairing our ecological
system upon which all human life depends. It is a movement that will recognize
the truth of the following statement: “Nothing is more important to human beings
than an ecologically functioning, life sustaining biosphere on the Earth. . . .
We cannot live long or well without a functioning biosphere, and so it is worth
everything we have.” Those are the opening sentences of a powerful new
manifesto, “Law for the Ecological Age,” authored by attorney and biochemist
Joseph Guth and published in the Vermont Journal of Environmental Law.
At the same time, this environmental human rights movement will
take up with equal fervor the task of divorcing our economy from its current
dependencies on chemical toxicants that are known to trespass inside our bodies,
without our consent, thus violating, as some have argued, our security of
person. Our current environmental regulatory apparatus does not require rigorous
toxicological testing of chemicals as a precondition for marketing them, as we
do, for example, for pharmaceuticals. It also makes it very difficult to ban
chemicals once they are in commerce. Of the eighty thousand synthetic chemicals
allowed into the market, exactly five have been outlawed under the Toxics
Substances Control Act since 1976. Our current environmental regulatory
apparatus allows economic benefits to be balanced against human health risks. It
fails to take into account the fact that we are all exposed, to use Rachel
Carson’s words, to a changing kaleidoscope of chemicals over our lifetimes and
not just one chemical at a time.
In umbilical cord blood alone, 287
different chemicals have been identified, including pesticides, stain removers,
wood preservatives, mercury, and flame retardants. Our current environmental
regulatory apparatus does not take into account the timing of exposure. And yet
the science clearly shows that toxic exposures during key moments of infant and
child development—especially during the opera of embryonic development—raise
risks for harm in ways that are not predictable by
dose.
Benzo[a]pyrene, an ingredient in tobacco smoke, diesel
exhaust, and soot, can damage eggs in the ovaries. Exposure to pesticides in men
can reduce sperm count. Thus, our environmental policies may be eroding our
fertility. And if a pregnancy is achieved, exposure to certain chemicals raises
the risk that it will be lost through miscarriage, or what we in the scientific
community call spontaneous abortion. Evidence suggests that the pesticide
methoxchlor has this power, as do certain chemical solvents.
And
here is where I am interested in engaging the pro-life community in dialogue,
because whether you see this problem, as I do, as a violation of women’s
reproductive rights, or whether you see this problem, as many members of my own
family do, as a violation of fetal sanctity, maybe we can all agree, pro-life
and pro-choice, that any chemical with the power to extinguish human pregnancy
has no rightful place in our economy.
When toxic chemicals enter
the story of human development during the fifth and sixth months of pregnancy,
when the brain is just getting itself knitted together, the risk may be a
learning or developmental disability. Of the 3,000 chemicals produced in high
volume in the United States, 200 are neurotoxicants and another 1,000 are
suspected of affecting the nervous system.
Some chemicals, such as
PCBs, have the power to shorten human gestation and so raise the risk for
premature birth, which is the leading cause of disability in this country. After
birth, some chemicals, such as certain air pollutants, can retard the
development of the lungs in ways that impede later athletic performance. Some
chemicals raise the risk for pediatric cancers, which are rising in incidence
more rapidly than cancers among adults.
Some chemicals can raise
the risk for early puberty in girls, which in turn raises the risk for breast
cancer in adulthood. In short, chemical toxicants can sabotage the story of
child development and so make urgent the need for restructuring our chemicals
policy along the principles of precaution and green design. But toxic chemicals
do not only discriminate against children, they may also discriminate against
our elders. New evidence links environmental exposures to neurotoxicants to
increased risks of dementing disorders in old age.
So I am betting
that chemical reform will be a cornerstone of this new environmental human
rights movement that I see getting under way. I am betting that my children—and
the generation of children they are a part of—will, by the time they are my age,
consider it unthinkable to allow cancer-causing chemicals, reproductive
toxicants, and brain-destroying poisons to freely circulate in our economy. They
will find it unthinkable to assume an attitude of silence and willful ignorance
about our ecology.
In the same way, I look back on the life of
Rachel Carson—my mentor in all this, who died when I was five years old—and find
it unthinkable that she could not speak about her own cancer diagnosis, even
while dying, as I have written about my diagnosis here. Thirty years of feminism
lies between my life as an adult scientist and Rachel Carson’s. That human
rights movement has ended the silence around the personal experience of cancer
so that I have never had to fear, as did Carson, that my status as a cancer
survivor will be used to impeach my science.
And in the same way, I
look back on the life of Abraham Lincoln, whose portrait hangs in every
schoolroom in Illinois, and marvel that our economy was once dependent on slave
labor.
Unthinkable. I believe our grandchildren will look back on
us and marvel that our economy was once dependent on chemicals that were killing
the planet and killing ourselves.
Now I am willing to concede the
point that this environmental human rights movement that I am betting on is less
an evidence-based prediction than a mother’s fervent hope that my children will
never have to fear that the phone ringing on a sunny afternoon will bring bad
news from the pathology lab. I’m willing to admit that this bet is a wish that
my children will grow up in a world with a functioning Gulf Stream, and some ice
caps, and a few coral reefs. And some octopi for my daughter to write her first
book about. And some honeybees to help my son the farmer grow apples. It’s a
wish that his polar bear Halloween costume not outlast the species.
Wishful or not, I am determined to win this bet because my
children’s lives are inextricably bound to the abiding ecology of this planet,
which is worth everything I could possibly wager. An environmental human rights
movement is the vision under which I labor, from which I am not free to desist,
and which may, if we all work together, become a self-fulfilling prophecy.
May it be so.
