Why is there a water shortage all over the world? The reason why there are water shortages around the world is because we ignore issues and now this made the amount of clean water decrease. some issues that we ignore are how we leave water running when they are not in use. Another issue that we ignore is flushing drugs down toilets which makes it even harder to clean the water. The amount of drinkable water on earth that is used from nature comes from lakes and rivers. This is only like 1 percent of the water on earth the rest of the water that is not drinkable comes from the ocean. What are the specific issues that are we ignoring? Also think about the difference in the type of water found in oceans vs. lakes and rivers - how much of drinkable water is really available?
