Environmental Public Health


The medical and technological advances of the past few centuries have helped improve human life on Earth, but technology has also had some unintended, harmful effects on human health and the health of other living things in our environment. This collection highlights these issues, examines how we are identifying the causes and effects of these health problems, and how public health works to improve conditions.

  • Environmental Justice in Dallas

    Follow a Dallas community's fight to receive federal Superfund status to clean up the damage from a high-polluting lead smelter in this video segment adapted from Earthkeeping: "Toxic Racism." Hear from a reporter from the National Law Journal who explains some of the health effects of lead exposure and how after a cursory cleanup of a lead smelter site in West Dallas, the community was ignored, despite warnings from the Centers for Disease Control about elevated blood lead levels. Meet Luis Sepulveda, a community member who organized the West Dallas Coalition for Environmental Justice, which eventually succeeded in having the site win Superfund status.

  • Malaria Treatment and Prevention Strategies

    This video segment adapted from Rx for Survival examines malaria in sub-Saharan Africa, a disease that kills more than one million children there each year. It explains how a deadly parasite, a member of the genus Plasmodium, enters the bloodstream via a mosquito bite and how it multiplies once inside host red blood cells. The video reveals that drug counterfeiting has increased malaria's death toll, and that newer drugs, while more effective than older ones, are too expensive for most Africans to acquire. The video also highlights one simple and low-cost solution—bed nets—that can be used to combat disease transmission.

  • Contaminating the Rockies

    Learn how abandoned mines have been contaminating water supplies in the Rocky Mountains in this video from NOVA: Poison in the Rockies. Beginning in the 1850s, prospectors dug deep mines in the Colorado Rockies in search of precious metals. Today, more than 15,000 abandoned metal mines have filled with acidic water that carries away heavy metals like lead, cadmium, and zinc into mountain streams. In small quantities, some metals are essential to life, but in larger quantities they are toxic. Some newer mines include safeguards to make them more environmentally sound.

    This video is available in both English and Spanish audio, along with corresponding closed captions.

  • Greater Boston | Is Autism Genetic or Environmental?

    Conflicting theories about what causes autism are explored in this video segment from Greater Boston. Scientists still don’t have an answer, and while many focus on genetics, some suspect that environment may also play a role. Mark Blaxill, whose daughter Michaela is autistic, explains why he thinks the disorder is triggered by environmental factors. Dr. Martha Herbert, who studies the brains of autistic children, says that toxins like metals, pesticides, and PCBs have all come under suspicion. But other scientists, like Dr. David Miller, say the key to autism lies in a person’s genes.

  • Heart Disease: America's Leading Cause of Death

    This video adapted from The Hidden Epidemic: Heart Disease in America examines the environmental factors that decades ago made heart disease the leading killer in America. While its root causes were unknown at that time, today, researchers can trace the problem to changes in the American lifestyle after World War II. Postwar prosperity led to more sedentary lifestyles and fattier diets. And cigarettes, which were introduced to soldiers during the war, became broadly popular. Researchers believe that the epidemic can be reversed if people eat healthier diets, exercise more, and stop smoking.

  • Greater Boston | Can Organic Farms and Mosquito Control Coexist?

    This video segment from Greater Boston examines the issue of spraying pesticides to combat disease-carrying insects. Massachusetts had been planning to use aerial spraying to control the spread of eastern equine encephalitis, a disease spread by mosquitoes. Ron Maribett, an organic farmer, said that if the state sprayed pesticides it would harm his business. The state said it would avoid spraying organic farms, but Maribett would have to bring livestock inside for 48 hours and avoid harvesting crops for two days. Another resident of the area believed that the spraying was necessary, but that farmers should be compensated for any losses.

  • The Effects of Pesticides on Children

    This video segment adapted from Playing with Poison describes how children in the Yaqui Valley, one of the largest farming areas in Mexico, have been harmed by chronic exposure to pesticides. To study the long-term health effects of agricultural pesticides, anthropologist Elizabeth Guillette tested children in the Yaqui Valley. The children showed deficits in hand-eye coordination, visual perception, and motor skills. Children in a nearby area that uses little or no pesticides did not share these problems. In North American cities, Guillette saw similar patterns with children exposed to pesticides from indoor spraying and food residue.
