Climatic changes will alter natural vegetation, wildlife habitats, crop growing seasons, and the distribution of pests and diseases.
Scientists agree that air pollution from human activities is partly responsible for global warming.
Global warming will expose millions of people to new health risks. A reduction in this type of grassland extent could be damaging for animals such as the common reedbuck, sable antelope and serval, as well as birds such as the grass owl. Drought can also increase the potential for conflict between humans and wildlife over access to vital resources such as forage and water. Some savannah highlands of southern Africa may also be at risk. These highlands provide fragmented habitat and vital refuges for wildlife species such as grey rhebok, grysbok, mountain reedbuck, black wildebeest, bontebok and blesbok.
