Healthy Tomorrows

A video series interviewing experts from around the world on children's environmental health issues
On 3 August 2020 in Dakar, Senegal, Oumou Kalsoum Diop (centre), 18, walks with Fatim Thiandoum (left) and Astou Diallo, both 17, looking to conduct spontaneous interviews with people on the beach to be used as part of a documentary on democracy in the country.

Healthy Tomorrows is a video series interviewing experts from around the world on children's environmental health issues, how and why children are at the most risk, and ways to address the global crisis. 

These short videos are less than 15 minutes and provide a deep dive into different topics that might be of interest to policymakers, programme implementors and communities.

The video content has been made available for informational and educational purposes only. The views expressed in these videos are those of the individual or organization they represent and do not necessarily reflect the views of UNICEF. 


Lead poisoning

Even small amounts of lead exposure over time can have lifelong effects on children, inflicting irreversible damage to their developing bodies and brains. Therefore, prevention is paramount. 

The Healthy Tomorrows video series hears from experts examining the impact of lead on children and how to prevent childhood lead exposure. 

Howard Hu

How lead (Pb) affects children and lifelong health

Howard Hu, professor of population and public health sciences at the University of Southern California, examines how lead (Pb) impacts children and lifelong health. He explains the life course paradigm, where lead exposure can start in the womb and move transgenerational. Because of its insidious effects, the best solution to end childhood lead poisoning is prevention.


How to test for lead in the environment

Jack Caravanos, clinical professor of environmental health sciences at New York University, and Bret Ericson, adjunct professor of environmental health sciences at New York University, share a tutorial on how to use a portable X-Ray fluorescence (XRF) analyzer to test for lead (Pb) in the environment.

Paromita Hore

New York City works to end childhood lead poisoning

Paromita Hore, the director of environmental exposure assessment and education at the New York City Health Department, shares how New York City has developed a lead surveillance system that exposes how children in the city are being exposed to lead.

Gordon Binkhorst

Methods of addressing lead-contaminated environments

Gordon Binkhorst, a senior technical advisor at Pure Earth, explains different ways to clean up environments contaminated by lead. He discusses the differences between remediation and risk mitigation techniques, as well as different strategies that could be applied.


Extreme heat

Climate change is raising average global temperatures and increasing the frequency, intensity and duration of heatwaves. Populations everywhere are experiencing heat stress, which is contributing to significant negative health outcomes, particularly for infants, children, pregnant women, the elderly, outdoor workers and other vulnerable people. For infants, young children and pregnant women, greater heat stress increases the risk of adverse birth outcomes, chronic health issues and infant deaths.

Cecilia Sorensen

How heatwaves harm children

Director of the Global Consortium on Climate and Health Education at Columbia University, Cecilia Sorensen, provides her expert views on how children are uniquely at risk from extreme heat. She discusses how heat is a teratogen, affecting normal development. Therefore, it’s important to protect children from heat, using frameworks like ‘B.E.A.T. the Heat’.
