Check out this podcast containing Cameron and a scene from Avatar at 4:52: We are the insurgents at subMedia

It features a statement of Mr Cameron after his visits to the ongoing annihilation of the Canadian landscape in search for more oil. For those who dont know it, Canada holds some of the largest oil reserves on this planet. Bad thing though that that oil is in the shape of tar sands which have to be dug out in humongous mining operations dwarfing the Unobtanium mines of Pandora and the refining process poisons the rivers and lands of the Cree indians (you may remember them for saying "Only When the Last Tree Has Died and the Last River Been Poisoned and the Last Fish Been Caught Will We Realise We Cannot Eat Money").

Mr Cameron then actually talks about how this oil is a valuable resource in the energy starved future can serve North America to become independent from OPEC oil imports. So what is he saying, that it is better to crap in the own backyard than in someone elses? crap is still crap and Tar Sands mining is about the biggest crap around in terms of hydrocarbon mining:

Please, someone tell me that he had some goooood reason to say this - but it better be a really, really good explanation!!!
