I'm not sure how much more this'll be taking the thread off topic (if at all, it's concerned with oil running out right?

) but I think that it's worth posting.
I think LaruaFrog has hit the proverbial nail on the head and I'd just like to add to that with a theory I read a few days ago (Yeahh I'm one of those guys who reads the end of days theories for kicks

) So if you don't want to read either - A) My incoherant ramblings, or B) A nice little theory prophesising the end of life as we know it, then I guess you should stop reading
Okayy, onto the fun

I refer to this as the petri dish argument - it is a basic analagy of bacteria in a petri dish filled with agar to the human expansion on this planet. So...
...We've all done the experiments in biology (well I did for sure, only in my AS levels!

), you place a small bacteria culture into a dish filled with agar and over a few days you observe it growing at an exponential rate. Now the problem comes when about half the agar has been used - the bacteria culture has grown to such number that with only half of the agar left they cannot all be fed, which causes a huge portion of the bacteria culture to die off. The ones that are left are able to eat the agar but in far fewer numbers and never reach the same population.
Right...So that was the easy bit, for me at least, I find huge problems relating the right bits of the petri dish bit to the human race...So bear with me
The bacteria represents the human race
The petri dish represents the earth (I think)
The agar represents oil.
Now, 150 years ago the first oil well was drilled (I think! xD) and the human population was around 1.5 billion. In the present day the human population is 6.6billion and we've used roughly 50% of the oil on the planet. Now as oil is what our entire civilisation is built upon it seems right to say that the agar does infact represent oil. Applying the analagy to this, it shows that when half the resource runs out the population crashes.
Of course people will say that we have renewable energy sources, but I doubt that renewable energy can replace even 20% of the power oil gives. I may be wrong about that, if I am, please correct me
So to sum it all up...Civilisation as we know it's gonna end very soon!
/Analagy over sorry about the length ^^
So yeah...my view on this whole subject is that if Colin_T is correct (and let's face it, when's he wrong?

) then it's not just our fish we should be worrying about!
