In modern society, it is possible to do shopping, work and communicate via the Internet without face-to-face contact with one another. To what extent do you think this is a positive or negative development? 

There are many people who prefer to purchase something online all of the world, working from home and conversation with our friends and relative by social platforms such as Twitter, Facebook, Skype and so on become the essential part of our life. This challenge have positive and negative effect on an individual person and our society. I will discuss both of sides in the next paragraphs. First of all, If we look at the unfavorable aspects, the most important thing is destroying the personal relationships of people. When nation make community via Internet, they lose their civil touch each other. Furthermore, they cannot understand felling of others. Another bad side is that, people can't check the quality of products which they buy online. Lastly, working online is the one of the reason of obesity and some illnesses what related to psychology of society like stress, frustration etc. For example, nowadays the mental illnesses have increased sharply in many countries and in the opinion of the researcher the main reason is to spend a long time on the Internet and not be able to socialize. However, the internet is more useful recently. It protect our time and energy. People can get everything with a touch. People also saved their time with working online. For example, there are many people who lives away from their family due to long and tiring jobs. But online workers spend more time with relatives and manage their finance without moving. To sum up, use of Internet for shopping work and community can be seen both of positive and negative of our life and health. But, I personally believe that, using internet is mandatory nowadays, we only should spend time on internet for necessary act without forgetting our real communications.
