That is a very intelligent post i will give you 10 out of 10 for that. Seriously we have nothing to worry about in our lifetime (that is about 30 years for me), there are plenty of oil reserves left in the world. Do not forget all the gasfields in and around Australia that we know of and the many yet to be explored. Where there is gas there is normally oil below that.
