Do you not see some what of an allegory to what is going on in Iraq ?(the oil grab under the created terror threat). We see corporate military in many parts of the world paving the way for resource grabs.
Humans have been terrible stewards of the earth. Would you not agree. I think the movie paints an accurate picture in that regard. Trouble is people have been sold a scriipt to act out this way unconsciously. So in a sense it isn't their fault. They have agreed to the consumeristic model though.
