China is building quite a bit of the electronics product that is
used by the world. It seems that they are not willing to control what
comes back to their country and people are being bought, corruption.
Their government needs to make it stop, or create an industry where
workers can be protected while they work on recycling instead spending
on building submarines and other weapons. In other words it is up to
their government to protect their people. Years ago there was a barge
full of medical waste. It went to many parts of the US and other
countries and none accepted it. It came back to, I believe, NY state
where it started. How can anyone from other countries protect the
Chinese or Indians or Pakistani, if their own government is not willing
to do so? It was in the News a few days ago that Puerto Rico is
accepting a lot of Medical waste and it is being burned in the Island.
Neighbors are complaining about the smell. I am sure as countries or
regions develop, mature and get a sense of what is going on and are able
to vote they will choose what is best for them. If people are working
and are not being beaten or jailed because of their religion, race or
..., It is a big plus.

Just notice this article in reading Fortune magazine:
http://money.cnn.com/magazines/fortune/fortune_archive/2007/02/05/839919
5/index.htm

Shoveling IT - it's about electronics waste, and a dump in China:

"A health survey done last year by nearby Shantou University found that
of
165 children under the age of 6 examined in Guiyu, 82% had symptoms of
lead poisoning."

Against current wisdom?

"A vast majority of the e-waste comes from the U.S. and countries in
Europe
- despite rules established at the 1989 Basel Convention that banned the
trading of toxic materials. ... (The U.S. remains the only
industrialized nation that hasn't adopted the Basel guidelines.)"
