If This Metaphor for Climate Change Doesn't Change Your Behavior, Maybe Nothing Will

Questioning the power of individual choice.

Each time you purchase factory-farmed meat, buy a ticket to fly, or take an eco-tour, are you making the world a worse place?


Theron Pummer posed this question of ethical vagueness in a post for Practical Ethics. After all, humanity has gotten to the point where our questionable choices have tipped the scales to the point of causing global climate change. But our single actions are like plucking one hair, Pummer explains.

“Plausibly, no plucking of any single hair on my scalp would make me into a bald man. And yet, together, several thousand such pluckings would do the trick.”

In a more morbid example, Pummer writes about a more stylized version from Derek Parfit's book Reasons and Persons from the chapter Five Mistakes in Moral Mathematics. In this section, the author argues why “the share‐of‐the‐total view” is flawed and why we should “accept the marginalist view, which appeals to the difference made by each act, why we should not ignore either small chances, or effects that are trivial or imperceptible.”

“Plausibly, no plucking of any single hair on my scalp would make me into a bald man. And yet, together, several thousand such pluckings would do the trick.”

Consider a man lying down on a table with a cloth over his face. One person puts a drop of water on the cloth; nothing happens. But if 1,000 people each place one drop of water on the cloth, the man will gradually become uncomfortable to the point where the exercise becomes waterboarding.

“Each of the 1,000 people can, it seems, claim that their act made no negative difference at all, since the victim can’t tell the difference between adjacent settings (we can suppose there’s no phenomenological difference whatever to the victim between adjacent settings),” Pummer writes. “It seems there is vagueness about when the victim’s pain level increases.”

Yet, each act contributes in some way whether it's deciding to vote with your dollar and shop local rather than go to a chain grocery store, or unplugging a device once its done charging rather than leaving it plugged in.

“Here, and now, is where we live. We don’t think, or feel, globally. We don’t worry about others as much as we worry about ourselves. And we don’t worry about the future as much as we worry about the immediate.”

Pummer argues, “In cases where it is genuinely indeterminate whether your act makes the world a worse place, you have a moral reason not to perform this act. I’m simply thinking that it’s worth avoiding acting in a way such that it is indeterminate whether so acting makes the world a worse place.”

There are ways to mitigate this moral vagueness. Solutions include the SunPort outlet, which draws its power from renewable energy, and the Nebia showerhead, which cuts water usage by 70 percent.

However, making these choices or not isn't always clear to us, writes David Ropeik, an instructor at Harvard. “Here, and now, is where we live. We don’t think, or feel, globally. We don’t worry about others as much as we worry about ourselves. And we don’t worry about the future as much as we worry about the immediate.”

The Nobel-prize winning economist Elinor Ostrom argues that, contrary to the widespread theory, with the right governance, humans are likely to forge peaceful solutions to coping with resource scarcity.

Five foods that increase your psychological well-being

These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.

Mind & Brain

We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.

Politics & Current Affairs

For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
