What is life without modern technology? It is impossible to do many things nowadays without it. It helps us in so many ways that it's really hard to find one or two main things! Let's see...
One thing to consider is that people must communicate to other people. As the world grows, we must know what happens out there, so we can take our decisions and it would be hard to know about something happening in Japan right now without the internet, for example.
Apart from communcating, modern technology makes our lives easier to live as well! We have new medicines every day against the worst kinds of sickness. Even for cancer! We can move much faster and cheaper between places with our new cars also! That's all so wonderful!
These were only some examples of how modern technology is helping us! As I said before, there are many other things to say about it! If you want more information about it, watch Discovery Channel.
