Interesting numbers on the sustainability (or lack thereof) of the aviation industry

Posted 20 Feb 2014 / 0

Air Transport Action Group “Facts & Figures” I recognize that these statistics are being presented by an industry advocacy group, so they should be taken with some skepticism (I don’t have the time to fact-check them). But they are interesting, and damning enough of air transport (while also accenting our very strong dependence on this Read More

Do we need to delete to keep the web sustainable?

WNYC New Tech City “The World Would be a Better Place if We [DELETED] More” The title of this piece is a bit misleading, because on the cognitive side it is really unclear to me that forcing ourselves to memorize things would make our lives better (those who know me know that I am “anti-memorization”, Read More

Production on marginal lands can meet only 25% of our biofuel mandates

Posted 17 Jan 2013 / 0

Nature “Bioenergy: Biofuel production on the margins” & “Sustainable bioenergy production from marginal lands in the US Midwest” This is fascinating, and provides further evidence that even the smartest biofuel production methods are not going to be enough to mitigate our energy demands. In order to really get off of fossil fuels, we need to find Read More

Freakonomics takes the quantitative knife to how we produce and consume food

Posted 25 Nov 2012 / 0

Freakonomics Radio “You Eat What You Are” This piece delivers a much needed kick in the self-righteous pants to the locavore movement. It systematically disassembles the assumptions of the local food movement, ending by discussing the minimal quantitative ecological benefits of using the “I only eat local” rule. It pulls apart belief from reality, and Read More

UCS “Cooler Smarter” footprint calculator promotes lower carbon behaviors

Posted 15 May 2012 / 0

Union of Concerned Scientists Cooler Smarter This is a much more simple footprint calculator than the ones I use in my classes, but it might be useful for people who want a quick snapshot of the carbon impacts of their behavioral choices.

2012 Sustainability Crash Course at Pratt Institute

Posted 25 Mar 2012 / 1

For the second year in a row I participated in Pratt Institute’s Crash Course in sustainability, sponsored by the Center for Sustainable Design Studies. I once again gave my talk entitled “Ecosystems: Where they came from, how they work, and why they stick around“. Beyond speaking, I also got to attend a variety of interesting Read More

Using Ecological Footprints to Teach Sustainability

Posted 27 Nov 2010 / 1

Technically- and traditionally-speaking, an ecology course should not really deal too much with policy. A strict definition of ecology should limit the topic to the study of the interaction between organisms and their environment, and for decades now that has meant looking at how non-human animals and other organisms constitute ecosystems. Discussions of policy, economics, Read More

Reclaiming a Rigorous Definition of “Sustainability”

Posted 18 Nov 2010 / 0

The latest issue of Frontiers in Ecology and the Environment features a great guest editorial by David N. Laband and David B. South entitled “Walking the talk on sustainability”. In this short piece, Laband and South make a point that is brought to light far too infrequently: that we use the word “sustainable” in a Read More

Crade-to-Cradle

Posted 03 Jan 2010 / 0

I just finished re-reading William McDonough and Michael Braungart’s book “Cradle to Cradle”. For those not familiar with the 2002 book, it has become the “go-to” spiritual reference for sustainable design. I say “spiritual” because the book reads more like a manifesto than a set of instructions; if you are looking for a how-to guide Read More
