How will the could end?

     "The mark of your ignorance is the depth of your belief in injustice and tragedy. What the caterpillar calls the end of the world, the master calls a butterfly."(Anon). The truth is no one knows exactly how the world will end. I believe the end of the world as we know it is  inevitable. Honestly I welcome it look how corrupt we have become by money and pride. Where has the humanity gone? The government is not what it was. We are not free, we are driven my money and power. Don't get me wrong I don't want the earth to be destroyed . I just think we need a change and unfortunately I cant help but think that human kind is going to doom itself. The world is more concerned about war and what country is in the most power they can't see they are putting an end to everything. If another world war were to brake out everyone is likely to nuke themselves. Not to mention the fact there are many facilities working on engineering biological warfare that could potentially spread and kill the entire planet in weeks. If a virus like that is air born without breathing aperatus everyone is doomed.
