It is a inspiring clip that America recommends it to their young people. It mainly talks about the menace from population of China and India, the fast pace of occupation changing, the rapid development of Internet, the big explosion of information and so forth. All of this indicates that we are living in a epoch of fierce competition, which shocks me deeply. It is not only for Americans but is suitable for our Chinese. You must ponder for some idea after watching. It can be searched in the Internet.
