Are conservation scientists really ready to stop trying to save the more-endangered species because they're too far gone, as suggested by Rudd and the New Scientist? The survey actually suggests otherwise. A strong majority of the conservation scientists surveyed thought that the most vulnerable species should be the highest priority for conservation efforts: most agreed strongly that "the species with highest probabilities of extinction and ecosystems with highest probability of land-cover conversion should receive the highest levels of investment." That’s not cold-hearted triage, but its polar opposite.
Such a ‘heroic’ position is not unreasonable. It's perfectly legitimate to believe that as a society we ought to organize our activities to be life sustaining – for both humans and non-humans. We need creativity and innovation to meet human needs while preventing the extinctions of known species. We can reject any position that takes for granted the current structure or potential future trajectory of our economy. Costly expenditures on desperately-endangered species might be seen by some as a waste of money, but they can also be seen as a critical and appropriately expensive signal that our society is structured unsustainably.
This position does not conform to the prevailing 'rational' decision-making by which everything has its price. But for those who believe in sustainability, it’s perfectly rational.
Note furthermore, that in this case, the heroic position may actually be economically rational. Cold-hearted triage makes sense when resources are fixed (as with war-time medicine), but conservation resources are not fixed: they are a function of donors. And if donors are motivated at least partly by principle-based and heroic thinking, there are substantial risks to appearing cold-hearted and gains for those who attempt heroism. It’s unsurprising that conservation organizations have distanced themselves from cold-hearted triage thinking thus far.
We need conservation scientists and others to take informed, compassionate and, yes, heroic action to staunch species extinction.

Soon after the predicted End, the vast majority of us were still here. Like déjà vu, the next predicted Armageddon (note December 21, 2012) is likely to unfold like yesterdays and those already passed. Perhaps this Rapture was another mathematical mistake (the given reason for the first botched Rapture of ‘94 provided by Mr. Camping, the failed prophet).
More predictable was the immediate response of those who believed the end was nigh. As a BBC article reports, some “...followers said the delay was a further test from God to persevere in their faith”. Cue sceptic and atheist eye-rolling.
However, are any of us innocent of this sort of rationalization?
Here we turn to a classic study in the annals of psychology by Leon Festinger and colleagues. In 1954, Festinger et al. managed to infiltrate a doomsday cult named the ‘Seekers’ led by one Mrs. ‘Marion Keech’. According to Mrs. Keech, who was purportedly able to transmit messages from aliens residing on planet Clarion, the End would come by way of a great flood on December 21, 1954. Non-believers would perish, but those who held their conviction would be saved and transported to safety aboard UFOs. Though Mrs. Keech had already falsely predicted several other End dates, it only served to strengthen her followers’ beliefs when the dates passed harmlessly. Indeed, as the morning of December 21st dawned and none of the Seekers had been whisked away at midnight, the once insulated group began an uncharacteristic media blitz to promote their beliefs under the impression that God had spared humanity because of their strength of faith.
Intrigued by the response of the Seekers to the failed prediction, Festinger took his study to the laboratory. In Festinger’s 1959 experiment, Stanford psychology undergraduates were asked to complete, with little instruction, two very boring tasks, namely “putting 12 spools onto a tray, emptying the tray, and refilling it with spools, and so on” for half an hour and then, on a board “containing 48 square pegs”, the participants were told to “turn each peg a quarter turn clockwise, then another quarter turn, and so on” using only one hand for half an hour.
Participants were then assigned to either: a control group who did nothing; a group in which the participant was paid a dollar to instruct the next waiting participant on the nature of the tasks and describe their experience doing the tasks as “very enjoyable, I had a lot of fun, I enjoyed myself....”; and another group who was asked to do the same for twenty dollars.
After lying through their teeth, the one dollar and twenty dollar groups, as well as the control group were asked to rate how interesting and enjoyable they found the spool and peg tasks on “a scale from -5 to +5 where -5 means they were extremely dull and boring, +5 means they were extremely interesting and enjoyable”.
The result?While individuals in the control group unsurprisingly found the tasks boring, and the twenty dollar group found it a little less mind numbing, individuals who were paid a dollar somehow convinced themselves that organizing spools and turning pegs was exciting work!
The results illustrate a phenomenon known in psychology as cognitive dissonance. Cognitive dissonance theory predicts:
1) If a person is induced to do or say something which is contrary to his private opinion, there will be a tendency for him to change his opinion so as to bring it into correspondence with what he has done or said.
However, 2) the larger the pressure used to elicit the overt behaviour (beyond the minimum needed to elicit it) the weaker will be the above mentioned tendency.
In other words, twenty dollars was enough to pay for a lie but one dollar was barely sufficient, putting the one dollar liar in a strange situation. On the one hand they knew playing with pegs and spools was tedious yet had agreed to tell waiting participants it was fun and enjoyable for only a dollar. Clearly, they rationalized “I must have liked the task at least a little!”
...bringing us back to Seekers, the Rapture, and climate advocates. Often we act impulsively in ways that are incongruent with our internal beliefs and without anyone needing to pay us at all. And like Mr. Camping’s followers and Camping himself, we’re often forced to face contradictory evidence. In both these scenarios we are left with a sense of unease, motivating us to find ‘logical’ reasons why the Rapture failed to occur, or why it’s okay to fly around on airplanes for vacation even though we’re climate activists when we’re not on vacation. It’s not all that difficult to see how advocates for sustainable fisheries can indiscriminately gorge on sushi. Or why so many environmentalists just “needed” to buy their iPhone.
So while it’s easy to skewer and laugh at religious kooks, the conservation and environmental community would do well making case studies of their own behaviour, if only to better understand the challenges facing sustainability.
After all, people who live in glass houses shouldn’t throw stones.

A journey of a thousand miles begins with a single step. The size of that first step might matter a great deal if psychological research is any indicator.
As I write, Parks Canada is currently trying to protect Canada’s oceans through its National Marine Conservation Area (NMCA) initiative. We should celebrate this effort, but it’s worth asking if we’re jumping off the starting block with enough strength.
The southern islands of the majestic Haida Gwaii archipelago off the North coast of BC have recently come under NMCA protection. Only 3% of this conservation area, called Gwaii Haanas, has been designated as fully protected from commercial extractive use (e.g., commercial fishing). In last week’s Canadian Parks and Wilderness Society report, scientists recommended that 30% of all habitats – not just NMCAs—be protected.
Three percent might not sound like a lot, and that’s the point. A small first step might make it harder for us to get where we need to go.
If you’ve ever negotiated your salary and felt like you were being low-balled by an employer, you’ve likely experienced the well-known psychological bias of getting ‘stuck’ around this first number. This bias is known as ‘anchoring and adjustment’ and was first theorized by psychologists Amos Tversky and Daniel Kahneman (Tversky & Kahneman, 1974).
Just how powerful is this bias? Consider a fantastic experiment by behavioural economist Dan Ariely and colleagues (Ariely, Loewenstein & Prelec, 2006) in which individuals supplied the last two digits of their social security number. People were then asked whether they would be willing to pay the number of dollars equal to these two digits for a bottle of fine wine and to indicate the most they would actually pay. What they found was shocking: people who had social security numbers with the last two digits in between the range of 00 to 19 bid on average $8.64 while those with digits in the range of 80 to 99 bid an average of $27.91.
In other words, even arbitrary numbers can completely skew our judgment, usually without our awareness.
Three (percent) isn’t just a number. Like salary negotiations, negotiating for greater protection in Gwaii Haanas and other developing NMCAs may be slowed or stymied by setting the initial bar so low. We may get to 30% eventually, but having three percent ‘imprinted’ in our psyche, as Ariely puts it, may make take our journey the long way around. Focusing on the greater protection afforded the oceans through California’s network of marine protected areas and Australia’s Great Barrier Reef protection should be the standard to which we measure our progress.

The May 21st reckoning has been zealously touted by some, and ridiculed by others. We prefer to think that relevance can be found wherever you look.
He must be pointing at a true believer (http://www.rcgroups.com).
We Hope You’re Ready.
Today is the rapture. While true believers are rejoicing their ascendency to heaven and nonbelievers are either recoiling in horror, indifferent, finding business opportunities, or making fun of the whole story (who would do such a thing?), we – as environmental and conservation scientists – have conflicting thoughts on the matter.
Jesus comes back today after a two thousand year absence. A series of earthquakes will open graves of those who died in the past (zombies? If true then things may go completely differently then outlined below). True believers (about 200 million) will be taken to heaven and the rest cast down in shame to remain on a doomed planet. Undoubtedly the whole ordeal will lead to civil and industrial strife for those left behind. And – here’s the kicker – everyone else dies and is cast down to hell on October 21.
This is serious (http://www.motifake.com).
On the one hand, this is an unprecedented opportunity for nature conservation. Depending on what happens to the wretches left behind on earth, the entire biosphere will have varying (though in any case lower) . All other organisms not being made in the image of God will be spared the messiness of heaven and hell. With remaining humans dealing with issues of basic survival and infrastructure nonexistent, pressure on wildlife through pollution, introduction of exotic species and diseases and habitat degradation will probably go down (though hunting may increase with less certain food supplies). The entire ocean will effectively be put under one big Marine Protected Area. No more illegal trade for endangered animal parts. No more industrial carbon emissions. No more housing and industrial development leading to edge effects. All three components of Paul Ehrlich’s equation for human impact on the environment (Impact = Population × Affluence × Technology) will go down. With less dependency on technology and more so directly on the natural environment, will the value of ecosystem services increase?
Now that's a protected area (http://interesting-facts.info).
On the other hand, what happens after the five month period of a Godless World (something that isn’t clear to us) raises some problematic metaphysical and metaethical concerns. If existence itself is destroyed, nature – by definition – is also destroyed. However, if just people get cast down to hell and the world remains, that raises the truly interesting questions. If nature goes back to a pristine state but there is no one left to appreciate it, does it matter? Can you have value without a valuer? Because “pristine” necessitates the absence of humans, is this truly a desirable goal for conservation? Besides these fundamental concerns about the existence of intrinsic values, the other issue is that the world will lose those interactions between people and nature that are worth conserving. The ties to nature and deep sense of place that local fishers, farmers, and others that derive their well-being and livelihoods will be gone. Humans have helped shape the world that we admire, and human loss will lead to a very different place: it will be a return from a socio-ecological system to an ecological system.
Wait. We'll lose this?!?!
A Short (Serious) Digression on Prediction
The human attraction to eschatological stories is an interesting one. For one, it affects the religious and non-religious alike. Stories of biblical Armageddon are widespread, but works by scientists like James Lovelock and Paul and Anne Ehrlich also discuss “end-times” situations. Both sides may not have their most extreme predictions come through, but the scientists in this case have some evidence and insights worth considering (such as overpopulations contributing to increased starvation). The problem is that the evidence-lacking, religious “authorities” get more press, more followers, and more impact. There are countless stories to be found covering the “rapture” predictions, and people seriously believe it. These stories do affect people’s views and actions, and this has important implications for conservation. Why should any care or concern be put to environmental concerns when the world is ending soon anyway? Can this kind of mindset be successfully challenged and changed? Conservation is a real world problem with diverse issues to face. Many of the most pressing issues relate to human behavior. What can conservationists learn from doomsayers?
