Why are stairs used more than slopes?

Question

Stairs are harder to walk, and higher risk of injury than slopes (imagine falling from stairs versus falling from slope).

So why aren’t slopes used more commonly in buildings?

Even stairs-shaped escalators are more common than slope-shaped escalators.

**Edit:** By “slopes”, I mean “ramps”. Pardon my English.

Answer 1

Imagine a typical staircase in a house. Now imagine how steep that would need to be if it was a slope instead. Virtually unclimbable for most people. To create an acceptable gradient slope would require a much more space. The same goes for any other building.
