All elephants need a lot of space, sometimes roaming over incredible areas to find enough food and water to sustain them. But their habitats are shrinking. African elephant habitat has declined by over 50% since 1979, while Asian elephants are now restricted to just 15% of their original range. Once common throughout Africa and Asia, elephant numbers fell dramatically in the last centuries, largely due to the ivory trade and habitat loss. While some populations are now, stable others are not.
