Alright, I feel like throwing my two cents in, so here it goes.
In my opinion this is one of the stupidest things to complain about. I've read a lot of the comments and I will probably bring things up that have already been brought up.
But, ~LisaReyOfHope please do some research before posting stuff like this. Some of your replies are uneducated and make you look ridiculous.
As a society, we have to realize that children are being subjected to more adult material, I guess for lack of a better word. That is why sites like DeviantArt does not allow children under the age of 13 to own or operate an account here. Why? Because like it or not some people post what is basically in my opinion porn on here. And sadly some don't even have mature tags on them.
Girls are getting their periods a lot younger because of the foods we eat.Not necessarily from what is in them or the hormones that may or may not be in them. I believe you have to weigh at least ninety to one hundred pounds to get your period. This is why gymnasts and anorexics don't get their period often or at all. I have a friend who didn't get her period until she was 17. She wasn't anorexic, but just naturally tiny.
When you look at the pregnancy issues in third world countries and compare them to say the United States, it's not really a fair comparison. In the US, we have access to things such as the morning after pill, condoms, and birth control. Where as in third world countries, they are lucky to have malaria pills. So honestly, bringing up third world countries, is just silly.
Many people bring up good points here, such as sexual maturity, getting a period to have a child, hitting puberty at younger ages. Honestly, I think its disgusting that we allow shows like teen mom and 16 and pregnant to continue running. Girls think that if they get pregnant they can go sign up for the tv show and become famous. If you really want to blame something for kids being sexually active at a younger age, blame what the media has us idolize.
I do feel bad for girls who have the rare cases of hitting puberty at an extremely uncommon age. Yes, childhood is supposed to be all about having fun. And for most it still can be. A lot of children have to take on more responsibility then they should. It's a sad fact of life.
I'm not sure what causes puberty at younger ages, only that hormones that regulate puberty are being released earlier in some children. Is it in the food, the water, or what where they live? And of course along with puberty comes interest in the other sex. It used to be in the past that girls matured faster then boys. I'm not so sure that is the case anymore as kids are having sex at younger and younger ages.
Yes, there is a disease that rapidly ages a child so that they look like they are 70 at age 10. But their minds are still only 10 yrs old. There is also precocious puberty where a child reaches puberty early because of early releases of hormones.
