If  we take a look at the past , we can easily understand why   the world has evolved that much over the time : because of technology.It has came with so many progresses in different fields which improved people ' lives that it would be difficult to imagine how our ancestors used to carry out their activities. Let's take for example , the medicine field , more exactly the Computed Tomography(CT)   which helps taking  pictures or images in very fine slices through the part of the body and also  involve creating several sets of pictures taken in different directions and 3-dimensional (3D) pictures. In this way, not only the tumors can be discovered offering  the pacient a chance to fight with this fatal illness of our century,the  cancer , but also any other internal affection might be treated . Therefore, from this angle , technology certainly represents a need.
         
Moreover , we don' t have to wait a few days for out letter to be received, our messages are  now delivered in any part of the world just in one second, not to mention the possibility of  a video confer ence. Accountancing should no longer involve piles of paper as long as there are so many data collecting, processing and transmission programs , and drivers are easily guided to the destination by their GPS systems. Of course ,these are just a few examples , but I think this is enough in order to realize how important the technology is.
 
The problem occurs when people want to be in trend with the society , so they have to buy the latest mobile phones . Sometimes the main thought is:"What are the others going to think about my social position  if  I don' t have the X phone?" , but nobody actually realize that buying the newest fancy techologies we encourage their production and also their evolution, fact that causes more damage to the environment. Let's think more about our real  needs in relation to the Mother Nature and less about what will people say regarded to how modern or not we are. One more thing that ,in my opinion, wouldn't be neccesary for  our existence is represented by smartwatches, i mean, why do we need one? One day we will slowly come to forget how to read the clock , fortunately , not everyone can afford this kind of gadgets.The main point is  that there are lots of activities we can achieve without using all of  those modern technologies , protecting the nature at the same time . And if we can, why not try?Why not make a little effort in order to save this planet?
