Model suggests that warming climate will catalyze greater insect-pest crop losses

Posted 30 Aug 2018 / 0

Science “Insect threats to food security” Science “Increase in crop losses to insect pests in a warming climate” This is scary, especially since this is a global estimate that has never before been modeled. I found it interesting that the temperate-zone effects are most profound because the effects of warming are not so extreme as to lower Read More

Escape is a big risk in aquaculture

Posted 30 Aug 2018 / 0

Science “Chile’s salmon escape demands action” Feral crops and livestock can present potential invasive species problems on land, but it is easy to see how aquaculture would present even larger problems: although aquaculture does involve “domesticated fish”, those fish are far less dependent on human care than their terrestrial counterparts.

My ecological footprint for 2015-2016

Posted 08 Apr 2016 / 0

Ecological footprinting is a regular required exercise in my Ecology and Ecology for Architects courses. I ask my students to use the ecological footprinting tool created by the Center for Sustainable Economy to calculate how many earths their lifestyle would require to be sustainable. I also ask them to profile an older relative (for most students, a parent) Read More

Science & Sustainability at the Green Meadow Waldorf School

Posted 22 Mar 2016 / 1

On Monday, March 21st I had the pleasure of visiting the Green Meadow Waldorf School in Chestnut Ridge, New York to discuss the role that science plays in helping people to achieve the goal of a sustainable society. In a talk entitled “Pulling Humanity Back Inside the Boundaries: How Science Serves Sustainability“, I gave students some Read More

Without sustainability in our diets, we won’t be sustainable

Posted 07 Oct 2015 / 0

NPR Morning Edition “New Dietary Guidelines Will Not Include Sustainability Goal” Man, this is a bummer. If our dietary guidelines are simply aimed at maximizing our bodily health but not the long-term health of our civilization and the planet upon which we depend, what’s the point of these guidelines? I love how the meat industry Read More

My ecological footprint for 2014-2015

Posted 06 Apr 2015 / 0

Every year in my ecology courses I have my students complete an ecological footprint analysis of their own lifestyle and the lifestyle of an older relative. I have been asking my students to do these for each of the eight years that I have taught at Pratt Institute, so I have accumulated a lot of Read More

Cod gone on Cape Cod

Posted 25 Jan 2014 / 0

NPR Morning Edition “Why The Cod On Cape Cod Now Comes From Iceland” It is fascinating how “cultural” the alteration of this fishery turns out to be. Somehow “Cape Dogfish” just does not have the same ring.

Concentrated factory farming of livestock massively alters the phosphorus cycle

Posted 25 Jan 2014 / 0

NPR Morning Edition “How Mass-Produced Meat Turned Phosphorus Into Pollution” This short feature provides a clear example of how human agricultural practices massively modify nutrient cycles, decoupling what used to be inseparable: where animal feed is grown and where animals are raised. This separation means that we no longer have closed-loop agricultural systems. I would suggest Read More
