Once humans evolved from bacteria in the ocean to walking and talking people, they started asking “why?” Seeking answers to that question has brought us to the point that we are today, able to go to the moon, split atoms, eradicate deadly diseases, compose and perform magnificent music, plays, movies, books, and produce computer games, among other really neat things.
Of course, there is a downside to technological advancement, because it has also brought to the point that we can easily destroy the world. All it will take is for one insane head of a country with an arsenal of nuclear weapons to push a button. Then, there is the process that takes a little longer, but can also do the job, and that’s the destruction of our environment by the side effects of machines and processes that produce pollutants.
Those thoughts occurred to me as I watched David Christian’s TED talk “The History of the World in 18 Minutes.” You can check it out at http://www.ted.com/talks/david_christian_big_history?language=en .
