Your post says all of that stuff (calamities, pandemic diseases, wars, hunger) happens in your generation. I hate to tell you this, but that stuff has happened in numerous generations before yours! 
Sure! We all aware that those stuffs (pandemic, wars, hunger, diseases and calamities) happened in previous generations but I think what the op was trying to justify is the importance and relevance of technology and virtual world in this our generation which can not be totally dispute.
