I want to add one more thing...
I personally know a person who is CEO of an oil company in Houston, Texas. He will retire within two years from now. He told me that oil WILL RUN OUT within 10 to 14 years from now. He encourages people to rethink about their transportation. He wrote the letters to US cities to encourage them to build public transit system before oil runs out. He also told me that gas prices will skyrocket to more than 10 dollars within a year or two from now.
Once oil runs out, Americans will FREAK OUT for sure. I strongly urge anyone to rethink about their transportation.
It is exactly same idea that we would freak out if we don't have electricity or water anymore.
Oh! Speaking of oil running out... This film, I recommand anyone to watch "If... The Oil Runs out." More information about this film,
