Gas. We hate spending our money on it, but we just can't live without it, eh? "$20 Per Gallon" by Christopher Steiner discuses the changes that will occur in our lifestyles as the gasoline prices increase. Sounds boring? Of course it does, but it's not as bad as you think trust me.
Steiner argues that the demand for oil will gradually increase and will continue to increase as the global middle class expands and the oil that remains in the earth will be more and more expensive to locate and extract.
It's a book I would normally pass up because I do not like to discuss issues like the economy and such, but I am glad I read it. It affects all of us. We need to start making changes now, before they become something we are forced to do.
