Last month, MNN family blogger Jen Savedge reported that California regulators voted not to list bisphenol-A (BPA) as a chemical believed to cause reproductive harm — though BPA's been linked to "early puberty, childhood obesity, breast cancer and neurological and behavioral changes," according to eco-research nonprofit Environmental Workng Group.

Still, the controversial chemical compound's disliked by many environmentalists and eco-groups — and remains a a hot topic of contention — both in the U.S. Congress and in the California state assembly. In fact, the state assembly's expected to vote on the California Toxics-Free Babies and Toddlers Act (SB 797), legislation that would ban BPA from baby food and drink containers, within the next month.

That's why Environmental Working Group's now helped put together a couple events to rally Californians against BPA and for SB 797:

Los Angeles: Toxic Baby Bottle Swap and BPA press conference

Wed., Aug. 19, 10 a.m.

St. John's Well Family & Child Center, 1910 S. Magnolia Ave Los Angeles, Calif.

Be one of the first 1,000 parents at the L.A. event to bring an old baby bottle — and you'll be able to swap it for a new BPA-free baby bottle from L.A.-based company Green to Grow. Eventgoers will get to hear from Dr. Harvey Karp, a pediatrician and author of The Happiest Baby on the Block.

Sacramento: Rally, press conference, and lobby day

Wed., Aug. 26, 8 a.m. - 3 p.m.

Look for a 15-foot inflatable baby bottle to find the other activists at the event!

If you can make it, don't miss out on the special events — and BPA-free freebies. Californians can also, of course, email their assembly members and urge them to vote for SB 797!
