You are worrying too much. We have already developed alternate sources for fuels. However these costs more to produce and as the oil is used up, we will gradually switch to the other ones.
We already know how to make gasoline out of coal, natural gas, sea water and even air. However these will cost about $10 a gallon more that what we pay now. We merely use oil for now as it is still the cheapest source.
The oil producers know this and one reason the oil price has dropped so badly is that they are trying to slow down the changeover to alternate fuel sources. When oil was expensive research surged on the alternate fuels and countries like Saudi Arabia became terrified that we would get the cost of alternates down to the point that they would be stuck with all this oil in the ground and no customers.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
