The Mystery of Oregon's 'Dead Zone' 235
Roland Piquepaille writes "The area off Cape Perpetua on the central Oregon coast is now a gigantic crab and fish graveyard. It was first discovered in 2002, but according to the Christian Science Monitor, researchers at Oregon State University (OSU) have taken a close-up look into this coastal dead zone. And things are getting worse. A few weeks ago, the researchers measured the level of dissolved oxygen in this part of the ocean. They found that levels were 10 to 30 times lower than normal, down to 0.5 milliliters per liter, a characteristic of hypoxia. And because they have no explanations about this phenomenon, they're even envisioning a total absence of oxygen, or anoxia. Read more for additional details and pictures about this mystery."

Welcome to a successful Roland Piquepaille slashdot bait. He's a master of re-explaining the basic. In this case, he's speaking down to the reader from his intellectual pulpit.

This type of premature conclusion is, I believe, very damaging to those who want to have global warming taken seriously by the mainstream public (ie. Me). Leaping to the popular conclusion with no reason other than it being popular to blame frankly makes me doubt the professionalism of the researchers involved.
Maybe it's the over-logging in Oregon depleting the oxygen levels ("hypoxia" was the Word of the Day May 24th, 2004), or the number of $evil_utility_or_commercial_industry dumping toxic waste into the ocean, or perhaps if the media sweetheart "global warming" doesn't pan out, they can pin it on Saddam Hussein^d^d^d^d^d^d^d^d^d^d Bin Laden^d^d^d^d^d^d^d^d^d Iran's President whatsis name.
Whoever they are, we need to identify the culprit(s) and bring these godless killers to justice. Oh, wait, unless of course its us... in which case, market forces are sure to cause a "correction" in the system and all will be well on Wall Street once more.

. I don't think anybody's going to hold a farm responsible for polluting the environment because they used manure for fertilizer, and the only difference between chemical fertilizers and manure is that the cheaper version is made of feces.
Actually I think that can be part of the solution. From what I understand most of the feces from the pig farms are either dumped or buried, though some gets swept away into waterways with rain. Allowing the feces to compost though it can then be used for fertilizer then chemical fertilizers wouldn't need to be used so much. Also if they were allowed freerange, they could so in one location or field one year then moved to another the following year. The second year a covercrop could be sown, then the third grains or vegetables can be growth on it, without needing more fertilizers. Actually this is how some organic farms operate but the big agrobusiness farms would probably frown on it.

Most of the methods used by agro-business are employed because they increase productivity. Because of this the US produces enough food to feed most of the world. Going back to methods a few hundred years old, on a large scale, would probably have some nasty consequences that most people don't think about.
Now, what we need to do is find something better to do with all the pig crap that is accumulated. I know that for cows there has been some pretty nice research into using the methane rising from pits of manure as an eletricity source.
The general problem is just that there is a ton of pigs, and no management system for dealing with their waste. Even when you reuse it for fertilizer, at the first rain a large portion of it will wash off into the local river system. Finding a nice way to manage and process that that doesn't completely bankrupt the farmers would be a good step for the environment, rather than saying they have to switch over their whole farming method to being half as productive and catering to the elite who can afford to care how their pigs were raised.
