Since I can't possibly write an essay here, I'll give you some points to write about: 1. Fuel - cars & planes - important for shipping goods - economic effects if there is no fuel. 2.
Plastics - made from oil - how important it is 3. Dependence on foreign oil - must deal with 'hostile' or 'unfriendly' countries 4. Life without oil and gas - no plastics no (insert whatever fits) Use these (and Google them for more info :)) so you should be at least halfway through.
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.
