More than 20 percent of the world’s population live in ecological hotspots, places rich in biodiversity but often lacking basic government services. Population, health, and environment – or PHE – programs address compounding stresses in these areas by helping to meet people’s needs for basic health services, including reproductive health care; promoting food security and poverty reduction; and teaching sustainable natural resource management. [Video Below]
