or that the federal trade commission needs to regulate the use of claims about "biodegradable" on the labels/packaging of goods . . . very few consumers have the resources to "dig deeper" into the biodegradability of a specific product . . . cheers, craig

A hasty, unscientific review of definitions of "biodegradable" via the web suggests that there is some variance in the anticipated nature of the end products of biodegradation. Based on definitions I quickly browsed, the end products of a "biodegradable" item could include: carbon dioxide, water and biomass only; only organic material; harmless artificial materials; toxic products; or, apparently, microscopic particles of plastic.
The lesson I'm taking from Irene's posting is that a wise consumer of "biodegradable" products needs to dig deeper and find out what they biodegrade into.

I guess it depends on what press you read. I hear tons of stuff about this issue here in the US.
