Lead

Nicholas FreudenbergGUEST
poisoning affects the nervous system and the brain, so it makes it harder for children to do well.

Nicholas FreudenbergGUEST
And the groups who were effective in fighting against lead poisoning realized they needed to bring together several different constituencies.

Nicholas FreudenbergGUEST
the parents and families of children who were lead poisoned, who had a very high motivation for doing something about this problem in order to protect and restore their child.

Nicholas FreudenbergGUEST
The tenants of buildings where landlords weren't doing what they needed to do to protect their children from lead poisoning, cockroaches and rats, inadequate heat, a whole range of housing problems.

Nicholas FreudenbergGUEST
And that this was one more issue they cared about and it provided a vehicle for tenants associations and housing justice groups to reach more people and bring them together.

Now, Dr. Freudenberg, coalition buildings, appears throughout your work? What allows people with different backgrounds, priorities and identities to unite around a shared purpose? And what most often causes those coalitions to fracture?

Ivan WiseHOST
Now, we've talked positively so far, but as well as things which should be better known, is there anything really famous you wish was much less well-known?

Nick FreudenbergGUEST
Uh, I want to talk a little about the, uh, Fight for 15 campaign, and that was a workers' rights movement that looked to raise the minimum wage from $7 an hour, which was the federal standard, to $15 an hour.

Nick FreudenbergGUEST
The New York City and the state and the nation, uh, labor rights activists had been looking to raise the minimum wage for more than 25 years and had consistently failed because employers said, "We can't afford it.

Nick FreudenbergGUEST
It will lead to the loss of jobs." There was very little evidence to support that contention, but these were powerful players who could afford to support political candidates who endorsed that position.

So what are some of the barriers? Why don't causes get better at building that cross-class and cross-regional support? What's preventing them from doing that?

Brian LehrerHOST
I mentioned in the intro the executive order from Trump from just yesterday on vaccines, which seeks to break up the MMR vaccine into three shots and seeks to use the Justice Department to end vaccine mandates for kids entering schools how does your and obviously your book came out before that executive order but in the midst of trump and rfk's um current reign how do you think what you wrote about in a history book most applies to today

Nicholas FreudenbergGUEST
sure and i think what uh motivated me to write the book was the feeling, certainly more so after 24, but really over the last period that we in New York City and the nation face really a cascade of health problems that look as serious and worrisome to me as any I've seen in the 50 years or so that I've been observing public health.

Nicholas FreudenbergGUEST
We have the climate emergencies, the heating, the air pollution from wildfires, the outbreaks of explosive diarrhea, antivirus.

Nicholas FreudenbergGUEST
And so I was really concerned that there was concerted undermining of public health.

Nicholas FreudenbergGUEST
And I think the Trump administration, Trump and RFK, really illustrate that.

Nicholas FreudenbergGUEST
Because not only have they been undermining the science and the evidence that undermines public health, but they've also been cutting funding for Medicaid and SNAP, for example, throwing people off those two lifesaving programs that just move, that protect people from falling into poverty.

Nicholas FreudenbergGUEST
And as well as changing the recommendations around vaccinations, cutting what Medicaid reimburses for.

A Roadmap for Health Activists with Professor Nicholas Freudenberg

Nicholas FreudenbergGUEST
The book is focused on New York, but I think New York has a long history of being both a starting place of many of the most serious public health problems facing the United States and really the world, and also a cradle for public health innovation.

Nicholas FreudenbergGUEST
So my hope was by focusing on New York, I could learn lessons that would be relevant both from our successes and failures for other cities and other places in the world, including countries like Canada and the UK and South Africa and so on.

Nicholas FreudenbergGUEST
There are important differences among those places, but they face many of the same problems.

Nicholas FreudenbergGUEST
The second reason I wanted to write the book is from my teaching and my work in activism.

TJ TroutHOST
I want you to tell me about some of your victories and how maybe they can relate to the rest of us.

Nicholas FreudenbergGUEST
So I think there, I can mention a few issues I had the privilege of working on.

Nicholas FreudenbergGUEST
One was childhood lead poisoning, and a lot of groups from the Young Lords to housing and tenant associations have fought to reduce childhood lead poisoning, one of the most serious threats to children's health in New York City and in other parts of the country.

Nicholas FreudenbergGUEST
And over the years, New York City went from having very high rates of lead poisoning to much lower rates.

Nicholas FreudenbergGUEST
And that was because activists forced city government to pass stronger laws, to focus on getting landlords to change what they did, to check their apartments, to clean up and cover up leaded paint, rather than using children as the canaries in the mine to test for places that had lead poisoning.

Mark ThompsonHOST
I wonder if you could give everyone a sense of your activism and then where we are today and how, in a sense, that activism still holds a lot of hope.

Nicholas FreudenbergGUEST
It's a question that activists I work with, especially the younger folks and my students at the City University of New York, where I teach public health.

Nicholas FreudenbergGUEST
So I became active during the movement against the war in Vietnam in the 1960s and was active in a variety of anti-war, civil rights, and community struggles in New York City.

Nicholas FreudenbergGUEST
And I then was looking for a place to have a career and make a difference and got into public health.

Nicholas FreudenbergGUEST
And so for the last 50 years or so, I've been working, continuing to work as an activist, but also as a scholar and teacher around public health.
Mark ThompsonHOST
So these are successes you've made through these decades, and yet you make a central part of the ongoing questions the ways in which many of these efforts and activist efforts intersect and all can feed each other, I think.

And, and what were some of the th- the, the kind of the things that they did that you thought were-- obviously, you ne- you, you, you talk about the particular pieces of activism, but, um, you know, some of the other activities that they did that kind of pointed them out as different or, you know, uniquely, uh, sort of successful in their way compared to other stand-- other forms of health ac- health activism.

Nicholas FreudenbergGUEST
I'll, I'll tell two stories, uh, that I think illustrate, uh, the approach of the Young Lords.

Nicholas FreudenbergGUEST
One is around, uh, lead poisoning, uh, an issue I did some work on myself, uh, in the '80s, uh, and early '90s.

Nicholas FreudenbergGUEST
And what the Young Lords did was they noticed that rates of lead poisoning were much higher in Puerto Rican and Black communities.

Nicholas FreudenbergGUEST
Lead poisoning, uh, is, uh-- affects particularly children whose nervous system is, uh, very vulnerable to lead exposure.

Nicholas FreudenbergGUEST
And, uh, in the long run, it can lead to, uh, behavioral problems, retardation, and in the worst cases, even death.

Patti VasquezHOST
And I mean, like some of the things that you wanted that you were, you know, taking with you this entire journey that you want to share with us so we can learn.

Nicholas FreudenbergGUEST
So I was a student at Columbia, started in 66, and quickly got involved in the student movement there that was fighting around against the war in Vietnam and against the university's expansion into Harlem, taking over housing and public land and so on.

Nicholas FreudenbergGUEST
And many of us were concerned about the role that Columbia was playing in the world, in New York, and in Harlem.

Nicholas FreudenbergGUEST
And I think that experience was really formative for me, that when people get together, find allies, we work to create alliances with community organizations in Harlem, with anti-war groups in New York City and in other cities.
