Because we are all capable of being selfish, insecure, and defensive.  We are also capable of better, but not consistently enough to achieve world peace.

Yes everyone of them can live together peacefully if they actually live u to the principles espoused by their respective religions.  and the atheist, well he just wants to get along.

It is entirely impossible for there to be world peace on this earth. No matter how hard you try, there will always be somebody that refuses to obey the rules. Human instinct.

Because that would be costly, chaotic and just one big problem!  There are too many religions, cultures, etc...If all of these people were forced to live in one country, war would be inevitable and a lot of lives would be lost.  As long as people are different, there can not be world peace.  Sad, but true.

because most people are selfish at heart, and would rather be the suvivor, regardless of the well being of others...\nthey believe in survival for the fittest, and they plan to be that survivor...

There is not enough being done to stop the hatred and as long as people view others as a threat they are not going to help them.  It shouldn't be this way but the fact is that most people won't open their door to someone they don't know even if that person is in need...they don't want to get involved and that is sad.  Many an innocent person is hurt everyday because of ignorance but until people see one another as equals it is inevitable it will ever change.

It is a false assumption that most humans want peace. At our core, what we really want most is control. We want control over our lives, our freedoms, our cultures, our traditions, our resources, etc.\n\nAnything that threatens our sense of control leads to another basic instinct called fear.\n\nWhen humans fear something, they inevitably seek to destroy it. \n\nIn a world with unlimited human wants and finite resources, natural selection does not favor those peoples, cultures, and civilizations that only want peace. It favors those who want control.

Have you noticed that asking for human beings to simply love one another has caused other people to hate you?  You're going to get yourself killed by one of those "peace-loving" religious types if you are not careful.  Look at the examples set by other prophets; they get killed for saying let's be nice to each other.  Even if you are successful in bringing about world peace, some religious nut is going to say that you are the "anti-christ" and kill you.  The religious world does not want to hear your message.  The rest of us are already trying to live it.  Thanks for the good thoughts and try not to get killed for them.

Instead of trying to decide who is more morally just in this situation, it would be best to try and come up with a way to end it peacefully.  If one side "wins", then it will only cause further conflict.

The world is in chaos because people won't mind their own business and let others live within their own beliefs. People need to stop imposing their religious/cultural beliefs on others.\nThere are a lot of people who don't want peace, and others who are rich because of poverty, so not everyone wants the same thing.

Some people are just hateful and want to find any reason they can to dislike other people.  Color is just a very easy way to divide people.

The world will never be a peaceful place as long as there are material interest as a base of society,it's simple-people are greedy and that meeans that no matter their lack of need they will threat other people for their resources.It isn't fair yet it happens since the begining of the forms of human organisation.

There will not be peace in this world as long as there are two people left together to disagree.Such is the nature of the species.George Bush or no one else can alter human nature.
