POPs and Pubertal Timing: Evidence of Delayed Development

Endocrine disruptors have been eyed as potential drivers of a steady trend toward earlier puberty among girls worldwide in recent decades, particularly with regard to breast development.

The nation's most comprehensive, collaborative, and developed program is right here in the Bay Area -- called, fittingly, Healthy Parks Healthy People -- with the primary sponsors being the Institute at the Golden Gate, an NPS-affiliated nonprofit based in Sausalito, and the East Bay Regional Parks District. Another leader is the City of San Francisco itself, which is the first and so far only in the world to formally adopt the use of parks within its public health program.
