Hundreds of experts from around the world are gathering in the Cambodian capital to discuss health problems linked to the use of firewood for cooking.

In Sri Lanka, where nearly 80 percent of the population does not have a better alternative than firewood stoves due to their economic situation, many die from breathing in the smoke.
