During the last century the way we live changed a lot, this is partially due to all the new inventions and discoverings. However, it is common thought that not every progress made has actually improven our day to day life, moreover some devolpment even made things worse. I am a firm supporter of change and I actually believe that going forward in time we as humans tend to make the world a overall better place, for example, elevating life standars or finding new energy sources .
