I was reading an article on California’s Proposition 65 in a journal called “Environment.” I’m now wondering whether I dare cite an article that appears alongside the following ad:
(The citation is William S. Pease (1991). “Chemical Hazards and the Public’s Right to Know: How effective is California’s Proposition 65?” Environment 33 (10), pp. 12-20.)
After skulking around nytimes.com message forums and reading exasperating commenters on The Atlantic, I decided to enter the “argument-by-comment” war on climate change by posting a comment on a Jim Manzi’s current meta-discussion of the climate debate. Typically, when I read these things the particular discussion is either so out-of-date or so dominated by nutjobs that I don’t feel like it’s worth contributing.
I don’t really know anything about Jim Manzi. But on this particular blog the level of discourse was pretty high and the latest post was fewer than four hours old. Plus I had just attended the Gordon Research Conference on Industrial Ecology (about which I can tell you nothing or I’d have to kill you– well, let’s say, “sequester” you). So I felt both qualified and compelled to respond.
I used my real name and linked to my blog, so I decided I had better go ahead and own up.
My first industrial ecology paper has just been accepted for publication in “Resources, Conservation, and Recycling,” titled “Material Flow Analysis of polyethylene terephthalate in the US, 1996-2007.” Polyethylene terephthalate (PET) is the “#1″ plastic material used to make bottles for soda and bottled water, as well as a steadily increasing stream of clamshell containers. It’s the most-recycled plastic. (update: available online as of May 15, 2010: doi: 10.1016/j.resconrec.2010.03.013).
Here’s the abstract:
