The main causes of water scarcity are:

Overuse of Water: Water overuse is a huge issue that a lot of people are dealing with. It may be overused on people, animals, land, or any other number of things. It may also be used for recreational activities without any care about the effects that it may have on the world around them.

Pollution of Water: Water pollution is a huge problem, especially when you’re looking at areas that don’t necessarily have a good sewage system. Pollution can be anything from oil, to carcasses, to chemicals, and to fecal matter. No matter what it is; it makes a lot of issues for the people who may need to use it.

Conflict: If there is conflict over an area of land, it may be difficult to access the water that is located there. In the worst case scenarios, people could end up dying if they try to access the water in these areas (due to violence). This can result in a variety of other issues, including pollution, which we discussed in the previous point.
