The Carbon Footprint of Food

The Blue Plate in a Red-hot World (start time: 7:46) While adding cream to your morning cup of coffee, or digesting the hamburger that you grilled last night, you might not have been asking yourself, What’s the carbon footprint of these ingredients and meals? Understandable. Our guest today, ecologist Mark Easter, however, has pondered this question intensely for many years, when he grocery shops, plans his next meal, and researches. Easter is a so-called greenhouse gas accountant, one who measures the sources and sinks of GHG emissions from agricultural practices.
It’s a vexing and critical calculus. After all, agriculture generates more than 10 percent  of U.S. greenhouse gas emissions. Easter’s debut book,  The Blue Plate: A Food Lover’s Guide to Climate Chaos (Patagonia),  has just been published. It highlights not just the causes of our climate crisis, but also a growing number of farmers, ranchers and orchardists who are practicing low-carbon, soil-enhancing methods on their land, and as a result boosting their crop yields and revenues.

Characterizing Microbial Communities

dustMicrobesMicrobial communities are all around us: in our homes, gardens, oceans, even deep underground but their roles in the function of the biosphere are poorly understood. Today Beth spoke with Professor Noah Fierer, at the University of Colorado, in Boulder, who uses DNA to identify microbes in communities ranging from insect microbiomes to Antarctic soils. He has discovered lots of previously unknown bacteria, viruses, and other microscopic critters which are everywhere, eat everything, and perform surprising roles in ecosystems ranging from our guts to Antarctic soils. You can see more at the Fierer Lab website. And check out the New Yorker article on shower heads. With this episode we resume our series on Our Microbes, Ourselves.
