Thank you, @NickKristof, for finding just the right message to engage people about the current crisis in our reproductive health. #countdownthebook.
Chemical companies are as reckless as tobacco companies were a generation ago, says @NickKristof, or as opioid manufacturers were a decade ago. They lobby against even safety testing of endocrine disruptors, so we are all left to be guinea pigs.

Male sperm count is 59% of what it was in 1973. Testosterone has been dropping 1% a year since then too. The average male in the U.S. is verging on infertility. @DrShannaSwan.

After my own miscarriage, I spoke w/ dozens of women about infertility. But this isn't just a personal problem; it could be a global one. Sperm counts are on the decline & miscarriages are on the rise. Join us with renowned epidemiologist @DrShannaSwan .

Great interview with @fastlerner on my new book, Count Down. These cumulative hits create subsequent generations that are invariably less fertile. It’s a vicious cycle and should be a call to action. #countdownthebook #spermdecline #fertilitydecline #reprohealth.
I keep thinking about the last thing @DrShannaSwan said: "It’s a two-hit model. Or, for subsequent generations, a three-hit or four-hit model. Because you get the inherited contribution, and then you get your own life course contribution when you grow up"

I strongly agree! As stated in this important @nytopinion piece, “we need to highlight the need to invest in safer chemistry and alternatives to single-use plastic with the same scale and urgency that we are arresting climate change” @ArleneBlum1 @MJMulvihill . #GreenChemistry.
The challenges of climate, plastic pollution and chemical toxicity — which at first might each seem like distinct problems — are actually interrelated and require a systems approach to resolve, write @MJMulvihill, @ArleneBlum1 and Gretta Goldenman.

Thanks to the @NewYorker @enckj @PlasticsBeyond @billmckibben for bringing attention to the link between plastic pollution and impaired fertility and health, and its link to climate change. #reproductivehealth #plasticpollution #spermdecline.
Love this interview w/ @enckj @PlasticsBeyond by @billmckibben. Key takeaway to address climate crisis: stop burning things. Biomass, plastic, MSW, RDF: don't burn it. Burning stuff harms people & the planet, even in fancy incinerators. @GAIAnoburn.

ICYMI: @FriedaKlotz's book review of Count Down, w/ @ColinoStacey . "Swan conducts a tour of an average house, pointing to where the toxins reside. It’s a clever conceit because it both illustrates the ubiquity of these substances and offers practical tips on removing them.".
