From my point of view, I see little trend toward a "cleaner" planet. Granted, I'm not seeing the doom and gloom some of those media buys in the past predicted, but I do see a lot of steady erosion of available resources happening too.

Not surprised you mentioned that psilli - North America generally is one of *the* areas which are being severely damaged.
Got some pics taken in Texas years ago - in a large valley which was like a national park and rich in ecology/species. That whole valley (and it's a big area!) is now totally devasted. There are no leaves on the trees - they are all dying and little wildlife left.
Apparently the main source of the problem was emissions from oil refineries in that area and where the local conditions mean't that these emmissons ended up as a cloud of pollution over the valley. Sad stuff...
Sure mercury is a problem, but not alone in the cocktails fish are fed. Analysis of water from a large number of rivers (a US survey) showed common traces of chemicals - mercury, the residues of chemicals used in Viagra, birth control pills and (dammit - forget the brand name) - anti-depressants. So... we got the fish high on Viagra, but taking their birth control pills and some anti-depressants to keep em happy
