No, this not a Mac vs. PC rant. According to Jobs' biographer, he lacked the sheer brainpower of a Bill Gates, but had something far greater in many ways: genius, or at least ingenuity. And this knack is described in ways that resonate with our ENVS Program learning goals, including a creative blending of the humanities and sciences and attention to visual modes of thinking. So if you are still worried about your physics friends getting jobs and you getting nowhere, this Jobs may have a lesson for you.

Living Through the End of Nature by Paul Wapner presents a new way forward for environmentalism after the end of nature. Wapner argues that humans have altered the physical environment to such an extent that it can no longer be viewed separately from humans. Additionally, many argue that nature is just a social construction and never existed in the first place. Since popular environmentalism focuses on how humans can reduce their impact on nature, the end of nature presents a problem for the movement. However, Wapner argues that the end of nature will actually make the environmental movement stronger and more politically effective by making political debate less contentious and by focusing on the connections between people, landscapes, species, and narratives. Moving beyond nature will also soften the boundaries that currently exist, and protect the well-being of humans and the nonhuman world by focusing on opportunities that involve both, such as urban sustainability, social justice, poverty alleviation, and the rights of indigenous people. Overall Wapner's book is well argued and well supported by concrete examples. However, he continually presents wildness and wilderness in terms of otherness which leads the reader to question if he actually believes his own argument about the end of nature. Wapner provides good historical background of the environmental movement which makes this book useful for readers that are beginning to be interested in environmentalism, or potentially beginning students who would like to learn about different perspectives on the topic. I would recommend this book to almost anyone, though the academic style to Wapner's writing makes this book more appropriate for a classroom setting than for a popular audience.

I would consider this a must-read for those into the alternative energy side of things. While the energies it highlights aren't all new and exciting, the numbers game it plays is pretty key. This is no optimistic one-technology-solves-it-all piece, and it issues a key reminded that no alternative energy we have reaches the input/output energy found in oil. By my reading, key to getting into the next energy phase we should expect is energy reduction, and energy efficiency. Our efficiency numbers, both from a physics and an economics perspective, are awful. The guys behind the Rocky Mountain Institute wrote a book called Natural Capitalism, which offers some great insights into energy efficiency as it stands and as it could be, if anyone is interested in that side of things. One of my favorite aspects of increasing energy efficiency is how its good for economies and good for the environment - still, there is the worry that if it makes things too cheap, people will use too much (the book cites fuel efficiency standards that were so good the cost of driving dropped significanly, and so many more people drove than more energy ended up being used). There are tools to avoid that though. I digress, but still, an excellent view of where alternative energy stands as of now.

oh man oh man oh man. huge, invisible, underground networks that transmit electricity? sounds familiar... "I have long proposed that mycelia are the earth's "natural Internet." I've gotten some flak for this, but recently scientists in Great Britain have published papers about the "architecture" of a mycelium - how it's organized. They focused on the nodes of crossing, which are the branchings that allow the mycelium, when there is a breakage or an infection, to choose an alternate route and regrow. There's no one specific point on the network that can shut the whole operation down. These nodes of crossing, those scientists found, conform to the same mathematical optimization curves that computer scientists have developed to optimize the Internet. Or, rather, I should say that the Internet conforms to the same optimization curves as the mycelium, since the mycelium came first." -- Paul Stamets more: http://peakenergy.blogspot.com/2008/07/natures-internet-vast-intelligent.html

A challenge to the idea that vertical farming may be more energy efficient than traditional approaches. Like the debate around local food though, it bothers me that we focus on energy and/or CO2 emissions when we measure environmental impact. In a much bigger picture, I'm not even so sure that another agricultural revolution, like this, is really what's best for the planet in the long run.

Good points all. While the excitement about vertical farms is good for attracting investors, the economic realities of all the systems involved are definitely questionable. That said, the Economist left out some things that are worth mentioning, both for and against the idea. First of all, the use of hydroponics is thrown out pretty willingly and easily, but its hardly simple. For one, you're moving away from the use of soil (and fertilizer, manure, other related mediums) as the primary medium for agricultural production. We are simulatenously just realizing that we don't really know much about soil as a medium. And even with water we have the same problems. The "known unknowns" are pretty great either way, and scale plays in. Most hydroponics (though there are major exceptions) are run by research organizations or universities, which means there is a lot more free and regular support, particularly from the sciences, than most commercial operations will be able to afford. Its much easier, when things go wrong, to have a cadre of free sciences hovering around. As for "you can grow anything in hydroponics", speaking from work I've done with those systems, you can - but good luck with a lot of it. Plus water filtration becomes an issue, though there are biological ways of handling that (even then you're creating a very limited ecosystem - they can get thrown off ridiculously easily). On the other hand, while light inputs are definitely a notable consideration, light science and "light engineering" is making leaps and bounds. So while I'd say issues with light are writing it off just yet, I wouldn't count on that as the everlasting limiting factor. Along with the various spinning, rotating, window side containers there are also various types of windows, "light tunnels", and even the good ol' basic efficient lighting systems and such to consider. And design, rather than technology, can also contribute - several vertical farm designs "stagger" floors to reduce

shading from the building itself. Also, for anyone following alternative agriculture from the technology/commerce/urban ag side, there are two details the Economist got wrong. Sweetwater Organics, featured on NBC a few weeks ago, is already running a commerical hydroponics farm out of an old railroad warehouse. The nutrients for their water chemistry come from fish (poop), who are also raised in tandem with the plants, also for food. Also, at least one vertical farm plan has moved off the drawing board (sort of) into fundraising stages, and the land for it is cleared (both physically and legally) for building. This is at Will Allen's Growing Power, in Milwaukee, WI. Will, the "father of modern urban agriculture" and a frequent visitor to the White House with Michelle Obama's "Let's Move" program, is hoping to build the five story building within a few years. It will be located (and provide food to) in a food desert, in one of Milwaukee's largest low-income housing projects. So the world will soon have a test case for this idea. Other cities may follow, but as far as I know the closest one (in terms of multiple floors of greenhouses) is planned for Toronto, and is at least two decades out - which probably means its anyone's guess whether it'll happen.

In lieu of ENVS symposium, I'm very interested in how the physical environment shapes the people that live there. This article discusses the role of place in the recent Wall St. protests and other movements around the world.
