For example, when I go outside the first thing that I take with me is a mobile phone at least only for a small reason to check the time. I think the person who does not have a mobile phone is not a person is an alien. At the same time, students use mobile phones in the school, causing ineffective learning environment for themselves and other students. From my experience, I can say that it is very distracting when you are trying to concentrate on the subject in class and when suddenly someone's phone starts ringing. It disrupts the teacher and makes it harder for me to learn. In addition, some people use their phones in the cars. They talk on their mobile phones while driving, and this can sometimes cause car accidents. Mobile phones change the way people do certain on a daily basis. .
There is also a great improvement in military technology. People create new weapons, new military vehicles, that can be useful and at the certain times harmful for the humanity. Some people believe that nuclear weapon is not an aggressive weapon, but on the contrary, is the weapon to save the world. Nuclear weapon restrains people from using it and can prevent from the war. If you think, what country wants to a have a nuclear war? I do not think that any country would want to have it. On the other hand, it can be very harmful if some people decide to have a nuclear war. Nuclear weapon is not going to choose who is innocent and who is not. If it happens to be used, no one will survive from it. .
One of the other new technologies in a modern world are the supplements for the food and artificial products. When I was a little kid, my grandmother told me to go to the grocery store to buy some food. I remember that the grocery store that I went to was so small and so empty that I did not buy what I needed to buy. The worker told that they going to bring some more food in a couple days. I was very disappointed that I did not get what was need.
