The launch of Microsoft Vista may initiate a massive wave of computer obsolescence. Where do we put all the refuse? Take a guess...
Guiyu, China
These women are picking through computer wires that have been exported to rural China for disposal. Once sorted, the wires, insulated with PVC and coated with brominated flame retardants, will be burned and emit carcinogenic fumes (polycyclic aromatic hydrocarbons and dioxins). That's why we export them.
According to the Basel Action Network, a toxic-dumping watchdog group, more than 50% of obsolete computers are exported to developing countries either whole or dissassembled, where they are processed and disposed of in ways that would violate environmental standards in the First World.

Or, offer it to a local Linux nerd, who may happily replace the old computer's operating system and give it many more years of productive service...
Isn't that mostly due to incompetent burning? As far as I know, temperature is the key. If the temperature is high enough you don't get any dioxins.
(I'm from Denmark where we burn almost all household trash before storing the "ashes" in landfills -- it takes up only about 10% of the space that way -- and the burning has been made surprisingly non-polluting.)
I have to assume that the abovementioned is not the sort of place where they enforce responsible burning. Indeed, I'm just speculating, but I expect that's one of the main reasons they're exporting all that waste...
