So for example, in the United Kingdom, the incidence of childhood leukemia has risen by 20 percent just in a generation. Please try again.Success! But what atrazine does is it turns on an enzyme, the machinery if you will, aromatase, that converts testosterone into estrogen. This is our issue, because we collect these compounds our entire life and then we end up dumping it and dumping them into our unborn children. 100+ collections of TED Talks, for curious minds .
It's not just my work in amphibians, but similar work has been shown in fish in Europe, holes in the testes and absence of sperm in reptiles in a group from South America and in rats, an absence of sperm in the testicular tubules as well. Topics. But just two weeks before that, the U.S. Senate refused to even debate the banning of BPA in babies' bottles and sippy cups. Again, we're seeing that trend across Europe, across North America.

Very similar statistic for childhood cancer in the U.S. How do you show that? And the frogs that are exposed to atrazine, the testes are full of holes and spaces, because the hormone imbalance, instead of allowing sperm to be generated, such as in the testis here, the testicular tubules end up empty and fertility goes down by as much as 50 percent. It's a compound that's found in polycarbonate plastic, which is what baby bottles are made out of. What would our unborn children say to us when they have an exposure that's happening everyday, day after day?But for the men here, I want to say it's not just women and children that are at risk. And as a result, when those rats grow up, their pups experience retarded growth and development because they can't make enough milk to nourish their pups.PJC: So when Tyrone tells me that the placenta is an ancient organ, I'm thinking, how do I demonstrate that? And in Europe, there's certain parts of Europe, where we're seeing a four-fold increase in certain genital birth defects. (Laughter) Frogs. And I believe, many scientists believe that pesticides are an important part of that decline. Not just in ourselves, but in wildlife like frogs and likely in other areas of our world as well. Tyrone B. Hayes (born July 29, 1967) is an American biologist and professor of Integrative Biology at University of California, Berkeley known for his research findings concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes and feminizes male frogs. It's a compound that's found in polycarbonate plastic, which is what baby bottles are made out of. For those of you who don't know, we're in the middle of the sixth mass extinction. No, I'm just joking. So when you develop a cancerous cell in your breast, aromatase converts androgens into estrogens, and that estrogen turns on or promotes the growth of that cancer so that it turns into a tumor and spreads.
Now I just can’t wait until I can see the film! TEDx Talks. Get TED Talks picked just for you. We already know that chemicals like DDT and DES and atrazine can also pass over into milk, again, affecting our babies even after their born.Tyrone Hayes: It was a surprise to me as well that I would be talking about pesticides, that I'd be talking about public health, because, in fact, I never thought I would do anything useful.
(Video) (Ringing) Old man: Placenta control.
The baby bottle scenario proves that we can prevent unnecessary exposure. Full bio Penelope Jagessar Chaffer - Filmmaker Penelope Jagessar Chaffer made the film "Toxic Baby," exploring environmental toxins through interviews and surreal imagery. What is it? And given the life of many of these chemicals, generations, years, dozens of years, that means that we right now are affecting the health of our grandchildren's grandchildren by things that we're putting into the environment today.TH: And what Penelope says here is even more true. PJC: So speaking of estrogen, one of the other compounds that Tyrone talks about in the film is something called bisphenol A, BPA, which has been in the news recently. I'll show you some statistics. And what's interesting about BPA is that it's such a potent estrogen that it was actually once considered for use as a synthetic estrogen in hormone placement therapy. And it's sometimes a weird place when the communicator becomes part of the story, which is not what you originally intend.
