Bob Ballard discussed in his TED talk about how we should explore our Oceans before we explore Space. I, however, disagree. Space exploration has not only given us a better understanding of the universe and how it works, but it has also led to many new inventions such as velcro and memory foam. While deep sea exploration could lead to many new inventions we use in daily life, I believe that the new tools invented for space could be re-adapted to be used in deep sea exploration.
Another point Mr. Ballard makes in his speech is that the ocean has a vast amount of resources. The same thing, however, could be said about space. Both environments have numerous amounts of resources that could be used for the betterment of mankind.
One last point I would like to make on whether we should be exploring space or the ocean is the eventual goal of personal space ships. Who doesn't want that?
