We live in a very special era. We are exposed to things today that 100 years ago we could only dream of. Think for example, 100 years ago, only lucky people living next to the ocean knew how a whale sounded. Today, every 3-year-old can tell you how a whale sounds and looks.
Technology has helped a lot to bring the world to our homes. In the beginning, there were photos, then moving picture and now live telecasts, showing things as they happen. We heave reached a point where we do not leave home and we think we can experience life through the screens of our TV and our computer.
But we cannot!
