As has been well-documented in recent years, certain populations and geographic regions can be much more vulnerable to environmental health issues like malaria and the use of DDT. Growing populations, with over 20-30% infected with HIV/AIDS, global climate change, and an environment that has experienced DDT applications for over 50 years, have led to increased outbreaks of malaria in the tropical regions of Africa.
