"Most Africans depend directly on agriculture and natural resources for their livelihood, and yet these livelihoods are threatened by the most important atmospheric phenomena in sub-Saharan Africa, which is climate change. Ironically, and relatively speaking, the continent suffers little from atmospheric pollution except in major cities where emissions from industry and automobiles are rising. Although the continent contributes least in terms of greenhouse gas emissions (GHGs) such as carbon dioxide, the main GHG responsible for global warming, globally the continent is the most vulnerable region to climate change."
