What are your views on adoption?

When I talk to my friends about how I want to adopt children instead of my own, they look at me weirdly and ask "Why don't you want to have your own kids?" or "That's stupid." I feel angered at them sometimes. Even though I'm quite young (14), I've seen what war and natural disasters can do to our world, and that includes orphaned children. I almost cried at all the children who were orphaned in Haiti and other places, and that's why I decided that I wanted to adopt because it hurts me to know that those kids don't have anyone who wants to take them in as their child, and they are always left with the fact that either their parents were ripped away from them, or their parents just didn't want them. I almost cry thinking about all those kids who yearn for a parent, but they're still stuck in their orphanage and they don't have a parent. I really do feel so sad for those children because they have to endure all of that pain, and it makes me even sadder to know that some of those children have grown old enough to remember it, not like the orphans that are adopted as infants. What do you think about it?
