That was an interesting article. Water contamination can be a big issue not only for the people who drink undisclosed toxins but for creatures using the water running off into the ocean. Most larger rivers all have a low oxygen level area near the river delta that you can see clearly from space photos. Last time I looked for such photos I could no longer find them. I personally think disclosure of such things should be a priority.

Fuel cells really sounded like a good idea. I think that they were costly to make and funding wasn't there for lowering the cost and improving the technology. It actually surprises me that we aren't using a lot more low polluting technologies at this time.
