A few years ago, when I began questioning what it really takes to write and publish in our digital era, I wondered about electricity’s true costs. I learned that on average, in order to light, heat and cool our homes; to refrigerate and cook food; wash and dry laundry; keep hot water available; send emails, talk on phones, watch tv and videos, write on computers and publish and read posts online, US households use 1,000 kiloWatt hours (kWh) of energy […]
What did we lose when we lost the stars?
Reading Dante’s Divine Comedy poses any number of challenges to modern readers. This should not, I’ll quickly add, deter modern readers from the attempt, which, in my view anyway, will more than repay the effort. In any case, one of these challenges may be the curious astronomical dimensions of Dante’s poem. You may know, for example, that each of the three cantiche that make up the poem – Inferno, Purgatorio, and Paradiso – ends on the same Italian word, stelle, or, in English, stars. Moreover, the […]
Connecting the Dots: Insane Trade and Climate Chaos
This blog is also available in Dutch, Greek, Italian, Russian and Spanish. Imagine a world where food routinely gets shipped thousands of miles away to be processed, then shipped back to be sold right where it started. Imagine cows from Mexico being fed corn imported from the United States, then being exported to the United States for butchering, and the resulting meat being shipped back to Mexico, one last time, to be sold. Imagine a world in which, in most […]
How smartphones are heating up the planet
When we think about climate change, the main sources of carbon emissions that come to mind for most of us are heavy industries like petroleum, mining and transportation. Rarely do we point the finger at computer technologies. In fact, many experts view the cyber-world of information and computer technologies (ICT) as our potential savior, replacing many of our physical activities with a lower-carbon virtual alternative. That is not what our study, recently published in the Journal of Cleaner Production, suggests. […]
Globalization’s Blowback
A recent study of air pollution in the western United States made a startling finding: despite a 50 percent drop over the past 25 years in US emissions of smog-producing chemicals like nitrogen oxides (NOx), smog actually increased during that period in the rural US West – even in such ‘pristine’ environments as Yellowstone National Park. Most of this increase was traced to “the influx of pollution from Asian countries, including China, North and South Korea, Japan, India, and other […]
The Great Deceleration
In 2015, a major study of 24 indicators of human activity and environmental decline titled ‘The Great Acceleration’ concluded that, “The last 60 years have without doubt seen the most profound transformation of the human relationship with the natural world in the history of humankind”.[1] We have all seen aspects of these trends, but to look at the study’s 24 graphs together is to apprehend, at a glance, the totality of the monstrous scale and speed of modern economic activity.
