Now? Teens have been getting pregnant since the dawn of man. its not a new problem, and I'm very skeptical own the notion that people need to be told that its not the greatest thing to do, because NO ONE in their right mind would want to have a baby on purpose when they are young. yes, they will love it and see it as a gift further down the road, but overall if you ask teens if they would want to be mothers and fathers at 16 or so, there will be a very loud and resounding NO. Kids and the general public aren't stupid or lost when it comes to simple things like this.
Also, I will venture a guess and say that a lot of teen pregnancies happen because birth control was ineffective or applied wrongly, which ONLY means that there needs to be sexual education at a lower grade now, since younger people are more sexually active, which isn't wrong at all as long as they are in consent and use the proper precautions.
This isn't rewarding them, its simply giving a pregnant mother the time to have her child and recuperate afterwards. Thats a GOOD thing! I think your idea that other kids will look to this and be lured into thinking that its ok is faulty logic. Not a lot teens are THAT stupid to be swayed so easily. I mean really, what half-intelligent teenage female looks to a pregnant girl and thinks "hmmm, I always wondered what forcing a basketball sized object through my vagina feels like, oh, and the extra weight and stretch marks too!". Thats not a very enticing thing, is it?
