How do you stop TPTB from deep sea drilling ?

Stop buying oil?

Its an addiction ! cold turkey would be some what extreme, cutting back on it would be a good start, while exploring other options to replace our dependency.

I,m more concerned about reforming political policy, that where we have to start - but how ??

China may account for 40 per cent of this year’s expected rebound in oil consumption and nearly 45 per cent of oil demand growth in the next five years, the latest monthly oil market report of the International Energy Agency (IEA) suggests.

Total oil demand in China, the world’s fastest-growing major economy, could reach 9.2 million barrels per day (bpd) this year, an 8.5 per cent increase from last year’s level, predicted the IEA, which advises 28 industrialised countries on energy issues.

IDK, OP, I have no positive ideas right now. We consume the smallest amount possible and so do most people I know. It is greed.

If we could dispose of world powers military monsters, consumption would drop dramatically, I,m sure we have the answers - but as you say greed has got the better of us, so hard lesson`s can be the only outcome, the future looks grim for this generations children.
Humanities path has a predictable outcome, fate sealed by our inability to change for the wiser.
