How did you get wherever you are at this moment?
In a car? Chances are, you drove, or were driven, there by car or bus — which was propelled by gasoline or oil.
Where did your food come from? Trucks or trains, powered by oil or gasoline distilled from oil, likely played a necessary part in its delivery.
Do you fly? Planes run on petroleum-based fuel, too.
And many of our homes are heated and/or cooled by oil.
