"With each interaction, Alexa is training to hear better, to interpret more precisely, to trigger actions that map to the user's commands more accurately, and to build a more complete model of their preferences, habits and desires. What is required to make this possible? Put simply: each small moment of convenience - be it answering a question, turning on a light, or playing a song - requires a vast planetary network, fueled by the extraction of non-renewable materials, labor, and data. The scale of resources required is many magnitudes greater than the energy and labor it would take a human to operate a household appliance or flick a switch. A full accounting for these costs is almost impossible, but it is increasingly important that we grasp the scale and scope if we are to understand and govern the technical infrastructures that thread through our lives. III The Salar, the world's largest flat surface, is located in southwest Bolivia at an altitude of 3,656 meters above sea level. It is a high plateau, covered by a few meters of salt crust which are exceptionally rich in lithium, containing 50% to 70% of the world's lithium reserves. 4 The Salar, alongside the neighboring Atacama regions in Chile and Argentina, are major sites for lithium extraction. This soft, silvery metal is currently used to power mobile connected devices, as a crucial material used for the production of lithium-Ion batteries. It is known as 'grey gold.' Smartphone batteries, for example, usually have less than eight grams of this material. 5 Each Tesla car needs approximately seven kilograms of lithium for its battery pack. 6 All these batteries have a limited lifespan, and once consumed they are thrown away as waste. Amazon reminds users that they cannot open up and repair their Echo, because this will void the warranty. The Amazon Echo is wall-powered, and also has a mobile battery base. This also has a limited lifespan and then must be thrown away as waste. According to the Ay

" The inequitable distribution of wealth, political knowledge, and free time in the United States gives wealthy individuals and corporations a leg up on ordinary Americans in the fight to influence public policy. But ordinary Americans have strength in numbers. And as DFP's polling suggests, there are no small number of progressive economic policies that a large majority of working people (from a wide array of regions, religious backgrounds, and ethnic groups) are ready to rally around. The trick is building institutions - and cultivating political leaders - that are willing and able to get that rally started."

Something as simple as black paint could be the key to reducing the number of birds that are killed each year by wind turbines. According to a study conducted at a wind farm on the Norwegian archipelago of Smøla, changing the color of a single blade on a turbine from white to black resulted in a 70-percent drop in the number of bird deaths.

The complexity of an ecological community can be distilled into a network, where diverse interactions connect species in a web of dependencies. Species interact directly with each other and indirectly through environmental effects, however to our knowledge the role of these ecosystem engineers has not been considered in ecological network models. Here we explore the dynamics of ecosystem assembly, where species colonization and extinction depends on the constraints imposed by trophic, service, and engineering dependencies. We show that our assembly model reproduces many key features of ecological systems, such as the role of generalists during assembly, realistic maximum trophic levels, and increased nestedness with mutualistic interactions. We find that ecosystem engineering has large and nonlinear effects on extinction rates. While small numbers of engineers reduce stability by increasing primary extinctions, larger numbers of engineers increase stability by reducing primary extinctions and extinction cascade magnitude. Our results suggest that ecological engineers may enhance community diversity while increasing persistence by facilitating colonization and limiting competitive exclusion.

"But national numbers in a country as big as the US can be misleading. For many African Americans in the Kansas City area, the spoils of a roaring recovery have passed them by."

"I like this piece by Kate Aronoff looking back on WPA "boondoggles" in the context of a suddenly much discussed job guarantee. A lot of people deserve congratulations for the suddenly much-discussedness of job guarantee proposals. People like William Darity, Darrick Hamilton, and Mark Paul, Pavlina Tcherneva, Randy Wray, and others have worked doggedly through years of winter to keep this (by no means new) idea alive while no major political faction in the United States was willing to give it the time of day. Now, all of a sudden, Democratic Party(ish) bigwigs including Kristen Gillibrand, Cory Booker, and Bernie Sanders are racing onto the bandwagon. Persistence pays (although perhaps not quite a living wage). Let's get this part out of the way. I'm for it, if it's well implemented. What about a UBI? I'm for that too, if it's well implemented. Do we need both? Well, they do complement each other: Pairing a job guarantee with a UBI would mitigate the risk that the "guarantee" would transmogrify under political pressure into a punitive workfare program. Pairing a UBI with a job guarantee would mitigate the risk that we neglect the broader project of integrating one another into a vibrant society, that we let a check in the mail substitute for human engagement. If we could get both a UBI and a JG, that'd be great. (Of course, if we did get both, we'd want the numbers to be different than either as a standalone.)"
