What is harming the cheetah's environment in the Savannah?

Human development? I think they need a bigger habitat because they are at the bottom, honestly, of the big cat food chain. So they need their own hunting space, their own large area to raise their young, etc. SO when that's diminished, they get closer to the leopards, the lions, the hyenas, etc.. all of which can easily overcome a cheetah if they so decide to eat their young, or even attack an adult cheetah. And if they attack a cheetah to get its prey (because they caught the prey so close to a lion's pride), they'll undoubtedly steal their food, or even kill the cheetah if it tries to defend the food.
