Umm.. That's an interesting topic.

For one thing, obviously, people can communicate from all over the world, which can help keep families and friends closer to each other.

Uh, they give parents a sense of security for when their kids go places, they'll always have their phones for help if something were to happen, resulting in them being able to loosen the leash a little bit..



Haha, that's kind of a hard one.. Hope I helped some. :]How have Cell phones changed the world?
