Whoah!
Let's keep things in perspective. Shell managers don't eat babies, you know. Well, only on special occasions.
The Delta is a mess, alright, but how much of that is down to Shell directly is arguable. You don't suppose it has anything to do with the Nigerian Government officials responsible not paying, perhaps, the very closest attention to environmental matters, do you?
I remember seeing a pipeline erupt in flames at three regular intervals one sleepy Sunday morning, when I doubt that was Shell causing the damage.
It's too easy to reflexively blame Shell for all the problems of the Delta but it's just not that simple.
