What's so great about this world?

This question got me to thinking. Many people both on that thread and in real life say they refuse to have children because the world is a terrible place. I admit that I disagree. Yeah, there are horrible things in this world and sometimes they get me down too, but then I talk to my mom and she tells me about the people who rallied around her to help her get pregnant. She’s also told me about my biological father who only donated sperm because he wanted to help someone get pregnant. Hearing that people, even a guy who’d never met her, wanted my momma to get pregnant makes me think that this world ain’t so bad.

So, collective, how about you? Why is it worth it to bring a child into this world?
