Lack of water in the future may result in several problems. It may increase health problems. It often means drinking water is not safe. Lack of water also result in more international conflict. Countries may have to fight for water in the future. Lack of water would affect the ability to improve the economy. This is because many factories often need large amount of water when they are begining.
In my opinion, people should be careful not to waste water.
