The depth of our environmental concerns mimics our evolutionary heritage

(Early humans probably traveled only short distances and only worried about short intervals of time into the future.)

Last year at the annual meeting of the Western Political Science Association in San Diego, CA, University of Missouri professor David Konisky reported on the results of his survey of 1,000 adults regarding their environmental concerns in a paper titled "Environmental Policy Attitudes, Political Trust and Geographical Scale". “The survey’s core result is that people care about their communities and express the desire to see government action taken toward local and national issues,” said Konisky, a policy research scholar with the Institute of Public Policy. “People are hesitant to support efforts concerning global issues even though they believe that environmental quality is poorer at the global level than at the local and national level. This is surprising given the media attention that global warming has recently received and reflects the division of opinion about the severity of climate change.”

In other words, people are more concerned about what happens in their own backyard than they are about the global environment. “Americans are clearly most concerned about pollution issues that might affect their personal health, or the health of their families,” Konisky said. Global warming ranked 8th among the environmental concerns reported by the respondents.

Is this really an unexpected result? On the surface, it seems surprising that given all the media attention to the problem of global climate change (e.g., rising ocean levels, melting glaciers, demise of polar bears and penguins, mass extinctions, shifts in agriculture, etc.) that it would not rank as the number one concern among a sample of Americans. But thinking as an evolutionary biologist for a moment, something I try to do a lot, the results could be viewed exactly as expected.

Throughout the Pleistocene epoch, which lasted from about 1.8 million years BP until about 11,000 years BP, humans lived in relatively small nomadic groups, or clans, of related individuals. They probably did not live much past the age of 40 and they probably did not travel long distances. The landscape must have been a dangerous place, so I have to presume that individuals went only as far as they needed to obtain the requisites of life: food, water, animal skins for clothing, wood for a fire. Occasionally there would be a dispersal event to colonize new territory, but the world you knew was only as large as the area you walked during your relatively short life. What another hominid clan did three valleys away had no effect on your life whatsoever, and it seems likely that humans living 100 miles apart never even knew of each other’s existence. What I have briefly described here is what evolutionary psychologists call the “environment of evolutionary adaptedness” or EEA. That is, conditions of life during the Pleistocene were such that humans were selected to be adapted to that environment, where life was short and known distances and effects were spatially small.

But times have changed. Now, the lifestyle of Americans, or Europeans, or Chinese threatens the well-being of a Bangladeshi living on the coast through the effects of global warming and rising ocean levels. The demand for furniture in Japan made of tropical woods can eliminate the habitat and homeland for native wildlife and humans living in parts of Indonesia. Radioactive fallout from the Chernobyl disaster in Ukraine resulted in resettlement of more than 300,000 people locally, but the fallout was detected in North America. And on, and on, and on.

Somehow we have to rise above our evolved concerns focused on immediate issues of time and space, but I still do not know exactly how to bring that about. We are all at least aware of how local actions can have global effects, and that is a start. And many of us pay lip service to our responsibility to future generations. But it seems to me that overcoming the "small distance-short time" dilemma is critical to solving 21st century environmental problems. The evolutionary problem is simply this: what is best for us and our family right here and right now may be harmful to others further away and not yet born. This dilemma manifests itself over and over again. Recognizing it is a first step to overcoming it.

I hate irises

(Just look at this cheap, gaudy flower.  Disgusting.)

I am an avid gardener.  The action of putting a seed in the ground and watching what it becomes is truly amazing, and you don't have to pay for college when it grows up.  In fact, if it is a vegetable, you rip it out of the soil when it matures and you eat it.  Pretty cool.  If it is a non-edible flowering plant, you watch it grow until the day it begins to flower, and you admire it, or smell it, or brag about it.  But there are some flowering plants that are common in human gardens that I don't like at all.  I hate irises, for example, and peonies and gladiolas.

I have long known which flowering plants were on my hate-list; this list is many years old.  But what the heck is this aversion to certain plant varieties or species all about?  After all, I find all living organisms truly interesting and biologically beautiful, including the tick that causes Lyme disease and the mosquito that carries malaria.  So what is it about an iris that would prevent me from ever planting one on my property or buying them in a flower arrangement?

I think these plant dislikes must be an aversion based on childhood experiences or associations with these plants.  My mother had irises in her garden around the edge of our yard as a kid.  I always remember them not doing all that well.  They were often buried in weeds, falling over, and they just looked cheap to me--like inexpensive costume jewelry.  I think I hate glads because they remind me of irises.  And peonies, let me count the ways.  I grew up near Van Wert, Ohio, which at one time was known as The Peony Capital of the World, because of all the commercial peony farms in the area.  They used to have an annual Peony Festival with a huge parade; when I was in high school, the marching band that I was in used to march in this thing every year.  I remember it being hot and humid and exhausting on that day--all in the name of peonies.  My mother also had this plant in our yard and all I ever remember about this plant is the sticky flower buds and all the ants climbing up and down the stems all day.  Heat, humidity, ants, stickiness, and an uncomfortable marching band uniform.  I guess that would do it.

But the flower I choose not to grow or even consider growing is the rose, and this one is complicated.  During the last 20 years of his life, my grandfather became a rose grower par excellence; he had been an auto mechanic all his adult life.  He had a rose garden with over 300 varieties in it, all neatly arranged in raised beds, all labeled with their proper name on a tag that stuck in the soil in front of each plant, and complete with a large water fountain in the middle of the garden.  It was absolutely beautiful, and the Gavin Rose Garden was locally famous.  He gave talks at the local rose society, was written up in the local newspaper nearly every year, tested new varieties of roses sent to him by the big rose companies, and supposedly had a new rose variety named after him (although I have never been able to confirm this).  To this day, my two younger brothers, who are also avid horticulturalists, will not grow roses and have no desire to do so whatsoever, even though we have great memories of playing in that garden as young boys and admiring it as we got older.  (Actually, my youngest brother just told me that he has gotten into growing heritage rose varieties.  Traitor!)

I am interested enough in this question about plant aversions that I wonder if others have experienced the same.  Let me know.  Will an unpleasant interaction with some plant as a child cause you to dislike that plant for the rest of your life?  Do you outgrow such a thing?  Is an interaction even necessary to dislike the species? 

You know, one approach in gardening is to create thematic gardens: a herb garden, a garden containing only blue-flowering plants, a rock garden, etc.  Maybe I should have a garden that contains only plants I hate--call it the God-awful Garden.  I would plant irises, gladiolas, peonies, and a few rose bushes together in one bed and then I would treat it as badly as I could.  I would never weed it, or water it, or fertilize it.  I would walk on it regularly, let the dog urinate on it, and encourage deer to browse there.  Maybe, if the poor plants survived all of that, my aversion would change to admiration, and I would want to grow these varieties all over the property.  Ummmmmmm....nah!

Denial, conspiracy, and the state of the environment

(I just can't figure out where all the oil is going.)

We have all done it. We want to blame someone for nearly everything bad that happens to us. In the case of oil prices, there are several likely suspects. Exxon-Mobil is making huge profits, speculators are driving the price up because of their trading in oil futures, there is too much oil in the U.S. Strategic Petroleum Reserve, and China is hoarding oil.

In fact, a CNBC poll last year during the peak of gasoline prices showed that respondents believed that only 15% of our oil problem was due to consumers; the remaining 85% believed it was due to speculators, OPEC, President Bush, Congress, or big oil companies. It could not possibly be the case that demand exceeds supply, because that would mean that they, or we, or I am using too much oil. If we are using more than can be produced, that might mean that economic growth has a limit of some kind, and that is nothing we have ever had to contemplate.

In fact, we still reject the notion that there is a limit to growth, because, if true, it would adversely affect all types of measures of our “quality of life”: the creation of new jobs, the increase in the value of my stock portfolio, the nation’s GDP, same-store sales this year over last year, and so on. We reject this unpleasant scenario and replace that specter with an attempt to find out who is doing this to us. Once we identify the criminals, we can alert our government who will punish the offenders or pass new legislation and, thereby, fix the problem, or so the thinking goes.

On the other hand, that same week I heard three “experts” on financial markets, all of whom I have come to respect over the past 8 years, come down on the side of basic supply and demand as the fundamental cause of high oil prices---Warren Buffet, Jim Cramer, and Boone Pickens. Pickens, the legendary oil man from Texas, actually said that the world can produce 85 million barrels of oil per day at present, but the global demand is currently 87 million barrels per day. And the International Energy Agency report released earlier that week estimated that by 2030 we will be able to retrieve about 100 million barrels of oil from the ground per day, but the demand then will be about 116 million barrels per day. If the latter number is greater than the former, then there will be demand pressure on the price of oil. Of course, this is not to say that speculation has nothing to do with the exact price of oil at any given moment, but as the adage goes: “Speculation gets the price of a commodity to where it was going anyway, only faster.”

I hear this same conspiratorial sentiment when discussing global climate change with the man in the street. It is all a scam perpetrated by ivory tower scientists and left-wing liberals like Al Gore and weirdo environmentalists. Someone is lying to us because THEY want US to behave differently, so THEY can benefit from our changed behavior. THEY are making up this grand story so THEY can become rich and famous. If THEY were correct that humans are causing climate change and this change is going to be bad for us, then WE would have to do with less, WE might have to curb our growth as a society, WE would have to drive less or drive smaller cars, or WE would have to turn off the lights frequently. THEY are doing something to US!

It should be obvious at this point in this little tirade that I believe as Pogo stated several decades ago: “We have met the enemy and he is us.” There is really no one else to blame for this state of affairs but us: our individual consumption and, likewise, the collective consumption and waste of a huge and growing human population currently numbered at nearly 7 billion. Remember that there is a net annual increase in the human population of about 80 million people per year; a decade ago, the net increase was about 100 million people per year. Currently, that means that every year there are about 100 million new people reaching driving age, regardless of what the driving age is in the country in which they reside. Now, most of those people will probably never drive a car, but I think you get the idea. It is tough to increase the supply of oil, or to reduce the effects of anthropogenic climate change, when the demand is increasing inexorably.

Supplies and prices of commodities or other necessities of life will not be resolved easily or quickly. And neither will global environmental problems like climate change or conservation of biodiversity. But I continue to believe that no problem is likely to be solved unless we understand the true cause. Pogo was a wise opossum.

The pooping Labrador retriever

(Zeus and DrTom don't know nothin bout no deer leg.)

I have a dilemma that I would like to share.  Our black Lab Zeus needs to go outside to relieve himself several times a day.  I know, I thought I had purchased the model that didn't need to do that, but I was wrong.  I even thought about not feeding the guy any longer so he wouldn't have to poop or pee, but when I do that he gets all lethargic and isn't any fun. 

But here is the real problem.  I want to just let the dog out when he has to go and let him in when he wants back in.  But Management insists that we walk him on a leash each time (the "we" in that sentence really means "me").  This seems ridiculous, because we live on 12 acres of forested land surrounded by more forested land.  Who wants to walk a dog in their pajamas when there is a foot of snow on the ground and it is 15 degrees, and we are over 100 yards away from the nearest house, and the dog likes to have a little freedom, and I enjoy watching him frolicing around the property, and the traffic on the road is not THAT bad.  But THAT is the problem.  Zeus will go down to the road when he follows the scent of deer that have passed through our woods.  My wife is afraid he will get hit by a car and I understand that.  So Management usually wins this argument, like she wins most of our arguments, and I walk the dog on a leash.

But sometimes, when it is really early in the morning, and my wife is still asleep, and there is almost no traffic, I cheat.  SHE will never know.  So on this frigid Saturday morning, Zeus and I got out of bed, and I let him out the back door.  In a few minutes he returned to the door to be let back in, but he was carrying something in his mouth.  (Dogs only carry things in their mouths.  But if you don't add that phrase, "in his mouth", the reader just might picture the dog carrying an item in some other way, and I don't want that distraction right now.)  When he stepped inside, I immediately recognized the item as a deer leg, a fresh deer leg with hair and skin and sinew and bone marrow dripping out from the femur.  Crap!  You see, there are often dead deer scattered about the landscape, and this Lab can smell one a mile away, and he loves the smell of deer. 

Zeus was so proud of this prize, but you see my dilemma.  If Management discovers the leg, she will know I let the dog out without a leash, and I will receive a tremendously forceful tongue lashing that I would really prefer to avoid.  If I just throw the leg in the woods near the house, the dog will simply bring it back again the next time I cheat.  Remember:  I didn't buy a poodle that never has to relieve themselves.  I bought a pooping retriever.  This leg will be like a piece of scotch tape that you can't get off your fingers.  Throw away, and retrieve, throw away, and retrieve.

So I put the leg in our kitchen wastebasket under the sink.  And as soon as the bag is a little more full, I will tie it up and take it to the can in the garage.  Zeus knows the leg is in there and I know the leg is in there, but Management is clueless.  Thank goodness she does not have a Lab's nose.  I know that Management thought it weird of me to be anticipating when she wanted to throw some trash in that wastebasket.  I immediately jumped to her side as she wiped her mouth with a napkin and said, "Here, let me throw that away for you."  And that is the way I played it, although I replaced her napkin six times for one bowl of soup.  I know she thought that napkin:soup ratio was a little over the top, but it worked.  I kept her away from the leg-filled wastebasket, and the secret was safe with Zeus and me forever.  Until Zeus returns for another helping of that carcass that is out there, somewhere.
