Narrator: This is Science Today. Indoor air pollution from cooking fires in Third World countries, cause an estimated 3 to 4 million deaths worldwide each year. Daniel Kammen, a professor in the Energy and Resources Group at the University of California, Berkeley, says women and children are much more affected by particulate matter caused by inefficient, indoor stoves.
Kammen: Women are exposed to so much pollution in this situation because they do all of the cooking, they put their face over the fire, children who are on their backs frequently in many developing countries are also highly exposed. Children are the most vulnerable segment of the population.
Narrator: Kammen conducted field studies in Africa to demonstrate that improved, clean-burning stoves, which cost only a dollar apiece, dramatically reduce pollution levels. And now the EPA is working to get these stoves in place.
Kammen: This EPA effort will provide funds for countries who are partners with the U.S. in this effort to popularize these stoves, explain their use, basically do the process we did in this rural community on a much larger, international scale.
