1. Global Warming- Rapid global warming due to climate change represents a severe threat to economic growth and development in southern Africa. It will exacerbate poverty and current inequalities in the region, but it can also serve as an opportunity to address these issues. The specific impacts of climate change on different sectors include:Food security, already a humanitarian crisis in the region, will be further aggravated by climate variability and climate change. Erratic rainfall is already increasing food shortages where droughts damage and destroy maize crops in southern Africa.Climate change will cause additional pressure on already unreliable water sources and health conditions will be particularly affected as a result.
2. Air pollution has direct and potentially hazardous impacts on human health. Air pollution includes two types: gas emissions, and particulate emissions. Non-hazardous, yet undesirable air pollution includes odors produced from certain manufacturers and fast food restaurants, etc.

Such pollution is most commonly associated with airports, highway and interstate traffic, large industrial facilities, and high volumes of truck and auto traffic on city streets. http://www.greenability.co.za/being-green/causes-and-impacts-of-global-warming/ http://www.lic.wisc.edu/shapingdane/facilitation/all_resources/impacts/analysis_environmental.htm
