And lastly (for now), just to stir things up a bit, check out this piece on Environmental Health Perspectives (EHP), a monthly journal of peer-reviewed research and news published by the U.S. National Institute of Environmental Health Sciences. This piece certainly raises interesting questions and offers unexpected claims. For example, in the Environmental Gains section it says, "Instead of recycling office paper, Gaines says, it should be used to generate energy in coal-fired power plants. 'Then you burn less coal and displace some of the coal emissions. Paper is a really good, clean fuel,' she says." I'd caution against jumping too quickly on the "rethinking" bandwagon, though, especially considering the fact that this claim is followed by, "But Dennison argues that Gaines' analysis glosses over an important factor. 'The wood has to be harvested from a forest and the forest has to be managed to produce the wood. And that set of management practices has important environmental consequences with regard to biodiversity, habitat, and so forth, that have to be counted...' " ... DUH. If this is where the debate is, I'm not convinced that these ideas have been fully flushed out yet. It's certainly important to challenge our dogmatic practices, but we also must make sure we've got our arguments all straightened out before we run with them. This is a place to start, at least. (There are, also, a number of other interesting points in this article, not all of which are so obviously undeveloped. I do recommend this piece if I've succeeded in interesting you with questions about "waste")

This article discusses the government's recently launched research on how anaerobic digestion, "a renewable energy technology that generates heat and electricity from waste organic matter," could possibly replace manufactured nitrogen fertilizer. They hope this will save money for the farmers and increase yield.

This is a neat setup and visual displaying environmental movements in conjunction with presidencies. Lots of cool facts included.

This article highlights the efforts to make Asian Carp, the next big threat to the Great Lakes (and the multi-million dollar fishing and tourism industries there) the next big food hit (or at least big enough to get people to fish them out). After all, as one expert says, "there's a worldwide need for cheap protein, and I think it's one of those things that fit the bill." But I have to say, I'm a little concerned. One, I know this is not a new strategy - people tried to turn garlic mustard into the next major salad ingredient, without much luck. But I think it could end up creating even greater threats in the long run. For example, if the idea is to get rid of the fish, it isn't a sustainable model for a business to follow. Why build a plant for a fish we're trying to get rid of? When the plants are built, the question changes: why get rid of the fish? In Darwin's Nightmare we saw how an invasive fish became a boon and blessing to the local economy. The Midwest is different, but some of the same forces are at play. Second, in my eyes the most legitimate argument against invasive, non-native species is that they don't provide ecosystem function. The ecosystem concept is rooted in relationships that help carry out nutrient/energy flow, etc... and these species don't really relate to others. By giving them a functional role as a food source, we give them a little more function to a species we really care about - us. Again, the plan to actually get rid of them may backfire as their benefits appear to outweigh their costs. The question does remain, is that a bad thing?

As most of us are aware, the world's population recently passed the 7 billion mark and we're scheduled to hit 9 billion by 2050. This article discusses 7 problems that we'll have to worry about as population continues to rise. We, as ENVS students, are already aware of these issues; water, climate change, and food security to name a few. However, some of the academics interviewed have very interesting ideas about solutions to these challenges (no-growth economy for example). For the feminists among us, Roger Short states that "We need to feminise the world and look first and foremost at the interests of women because they're the ones that are going to decide our future and it is their determination to limit the size of their families which will be the saviour of the world," which I thought was pretty interesting.
