> oil and plastics executives began a quiet campaign to lobby almost 40 states to mandate that the symbol appear on all plastic Yeah, but this was a really good thing (probably the only good thing the oil+plastic lobby has ever done). Those symbols are a godsend for DIYers; before we had them you could never know if a piece of plastic could be glued to (and if so, with what glue) or what kind of chemicals it could safely hold (as demonstrated in _Breaking Bad_!) Everything else they did was evil. But not this.
