There is enough water in the world. The world is made up of seventy-five per cent water. What that means is that there is less land than water. Waterways are important in war times and in trade efforts in regards to transporting goods and raw materials with valuable imported supplies.
I believe that there is more than enough water in the world. Humans have only explored 5-7 percent of the ocean and that goes to show you how much water there is the world. Roughly 70% of the world is covered in water. I don't think we will run out of water in our lifetime.
