Here's another map that reveals just how much humans have decimated wildlife. It reveals the historical range of lions in Africa, Europe, the Middle East, and Asia. The blue is where you can find them today, and it isn't in many places. Lions are now only situated mostly around central and southern Africa. There is also a small pocket of lions located in India, where they used to roam throughout the entire country.
You could probably point to just about any large animal on the African continent and make a similar map to this one, especially if they're a large predatory animal.
