Assuming that you accept the principles: a)babies are people b)it is bad for people who are unable to care for themselves to be without care c)teenagers would often be unable to care for their babies one reaches the conclusion that, if teenagers were to have babies, often they would be unable to care for them, and this would be bad. Therefore, reducing the rate of teenagers having babies is good (because it is preventing a bad thing, and not at the cost of another bad thing) Generally, teenagers are not mature enough to raise children by themselves, or, they are at least less well suited than someone a bit older would be.
