I’ve seen a study which found that the age of puberty (especially female puberty) is dropping rapidly. In 1860 it started around 16.8 and in 2010 it was 10.8. Why is that? Is there any explanation?

i watched a documentary on plastic that talked about this and it scared the shit out of me. there’s an ingredient used in receipts and water bottles called BPA. it used to me used as hormonal birth control but because of low amounts of estrogen it wasn’t very effective but they found that it helped preserve plastic better. however just touching BPA can expose your body to unnecessary levels of estrogen and children drinking from water bottles containing BPA is connected to early onsets of puberty in females.
