From your post, it sounds like you are not from Alaska, as I am, and also not familiar with drilling practices and procedures. With the newer technologies and directional drilling, a "pocket" of oil can be reached and tapped more than a mile away from where the actual drilling rig is actually located. Hence the pipe connecting the majority of those pockets will be under ground bringing the oil to the surface at a well head. From this well head surface pipe will have to be constructed to route the oil to the main pipe line. This of course will require some land, which I am sure is included in the 2,000 acres mentioned. The local widlife seems to appreciate these pipes, as there are many pictures out of them huddling close by for the warmth they bring into a very harsh, bitter environment.
As for the unmarked pristine environment, didn't the article provide you with an idea of just how little land we are planning on using for this project? The area set aside for ANWR is already larger than a number of states in the lower 48, and it is but a small part of what we call "The Great Land." Alaska is 1/5 the size of the entire United States, with more coast line than any other state, more natural resources than any other and most of us are willing to develop it al to help you and us.
Following your arguement about just how little oil ANWR will contribute, I guess it would only make sense to actually close down the existing pipe. After all, it only provides about 10% of the national need and surely we could engineer those kinds of savings into our all but nonexsistant energy policy. Closing down the pipeline would also eliminate ignorate, drunken fools from taking shots at it and spilling some 275,000 gallons of oil in my backyard. Then again, there will always be idiots doing stupid things and when you stop to think about it, almost any public facility or resource is vunerable.
On a little note, tourism is a major industry here in Alaska and they are encouraging us to invite every one up to visit the state this year. SO come on up, bring your family and go out to visit that last pristine location on the face of the earth. Plan on staying awhile, as there are no services available in the area. You might be able to fly into Katovick, and figure on a 4-5 day hike into the area. Bring lots of bug dope because the mosquitos will almost darken the sun as they swarm around your family. Please remember to leave nothing but footprints on your way out, it needs to be kept just as pristine for the next visitor.
