1.) Because we kill each other for no reason. Look at all the civil wars going on at this moment. It's just sickening.
2.) Beacuse we're greedy. People all over the world starve -even here in America, where there's enough for everyone- and nobody does anything about it.
3.) Because we're cruel. We insult people just because they're different.
Not everyoone is like this, mind you. But most people are.
