Changes in pressures on biodiversity, including infrastructure development and population pressures, land use change,
pollution and climate change, under 4 different scenarios from the Global Environment Outlook series using the GLOBIO 3.0 model.
Notice the similar pattern in Africa under all scenarios with varying degrees. This will have major impacts on the habitats and ranges
of the African elephants. The threat is particularly high in areas with large population growth and significant agricultural expansion
