Hi,
This is an interesting topic. In my opinion,it is not sustainable to rely on oil for much longer.
In terms of its damage to the environment, and also the unreliability of supply (ie-unstable countries such as Iraq).
I think a lot of our lifestyle is no longer sustainable.
We should spend less; consume less; eat less etc...
What does everybody else think?
