The Tragedy of the Marine Commons
I’ve made this parody before:
Give a man a fish, and he’ll eat for a day.
Teach a man to fish, and he’ll eat until the fish are extinct.
All indications are that our grandkids won’t be big fans of sashimi, as it will either be too expensive for them, or virtually non-existent, because we have driven the large fish species to (or near) extinction. We’ve been making fish smaller, and less plentiful for millennia. This is no huge surprise. We ate all the tasty North American megafauna when we got here too. We were hungry, and we didn’t know any better. The world and its resources seemed vast beyond our comprehension.
The situation today is tragic partly because we know exactly what we’re doing, and partly because we could be sustainably harvesting vastly more fish today than we are currently mining at an unsustainable rate, if only we could somehow contrive to let fish stocks rebound to their Pleistocene levels. At those very high (pre-human) stocking rates, the sustainable take would be enormous, but we would have to manage the harvest carefully with quotas (which we didn’t do the first time around, and which we are much better equipped to do now). Such quotas are sometimes discussed as if they were purely economic or political quantities, but in some important ways they are neither.
Does this look Freegan to you?
Why are labels so attractive? One word shortcuts for frugal thinkers. Am I a freegan? What would that mean exactly? Who curates the definitions of our cultural -isms?
Reading through the Wikipedia article on Freeganism (which is as close to a cultural consensus on anything as I think we get these days), it seems like I’m close. Except that I’m not fundamentally opposed to eating meat (it’s the environmental degradation, antibiotics resistance, health detriments, and massive resource consumption involved in meat production that get to me… but a little free meat from the dumpster? Tasty!). I also have a soft spot for shiny new laptops and other information technologies, and I believe in the greed based toolkit of money, markets, and open competition as a way to foster innovation. But I also love composting, and creative re-use, and free non-materialist forms of entertainment and recreation like reading, and writing, and cooking from scratch, and I believe that unmitigated greed, and thus so-called laissez-faire (or perhaps in many cases more accurately crony) capitalism, left unchecked, are in the end destructive forces. Greed and self-interest are kind of like dynamite: the right amount in the right place is a wonderful tool. Too much, or even small amounts in bad places, and you’ve got a mess. So how do I respond to an e-mail like this:

A Dumpster Diving Tally
We went dumpster diving by bicycle again and came home with $200 worth of Trader Joe’s fare.
I’ve itemized the food we got, with actual or estimated costs below.
Framing Embeds Values in Scientific Facts
At the Sustainability Symposium last night (which was nominally about water footprints (PDF) and this paper on the international trade in virtual water) we ended up “off topic” and talking about science communication, public outreach, and how policy gets made. Inevitably it seems like these conversations end up coming back to the issues from Chris Mooney and Matt Nisbet‘s Speaking Science workshop that SASS sponsored last summer.
There is huge discomfort for scientists in the fact that the way in which information is conveyed impacts how it is interpreted. The idea is at odds with the scientific ideal of objective facts and communication, but nevertheless it is true. A one liter glass plus 500 ml of water equals what? The glass is half empty. The glass is half full. The glass is twice as big as necessary to hold that much water. The same objective facts, different connotations. Different implications. Different frames. And sometimes, the frame ends up being a more important determinant of the listener’s reaction than the information the speaker intended to convey.

- Wal-Mart To Become Green Umpire – Wal-Mart arguably has more control over and insight into its supply chain than any other company on earth. The information they need in order to be able to force their suppliers to produce the goods as cheaply as humanly possible overlaps substantially with the information required to provide transparent information about the environmental impacts of those same products. Wal-Mart says they want to use this power for good… for telling, in condensed form, the sustainability back-story for their products. But will they tell the truth? Will it be transparent? Will it be verifiable? And even if it is… will their customers care? Might it change their customer base?
- Howtoons – A series of comics which both tell stories, and inspire kids to build their own toys and tools. Wonderful hacker propaganda.
- Where's the Real Bottleneck in Scientific Computing? – A story about a computer scientist talking to physicists who have hundreds of thousands of lines of code, and don't know what version control or unit testing is. Hmm. I guess I don't really know what unit testing is either.
- Software Carpentry – A Python based tutorial for scientists and engineers who need to learn how to (actually) program. How could it have taken this long to appear?
