I anwsered questions all day maybe someone can help me? anwser this question, thats been bothering me?

Try and try as I might I can't rap my mind around a anwser. I am pretty sure I've spent most of my life trying to figure it out, and always failing, but never did I stop looking for the anwser to my question, and now that I sit here in the age of the digital world. With the ability to ask my question to thousands of people I shake with fear and anticipation, of finally knowing the awnser. So I ask you all to give me your best try, Explain to me why it is that if the human race is capable of prolonging our own lives, why then do we seek to destory ourseleves, when all we have to is respect our planet, its creatures, its people, its life! Explain that to ME! why we kill eachother why we make stereotype's of people and judge each other wicked and wrong when we should all just be taking hits from a bong! tell me that people tell me why so many people are angry about there life, when all they need is hope that its going to be better? Where is that hope? Does America still Have Hope? Tell me
