Why is the world is thirsty？ The world is thirsty is mean that we don’t have enough water in the world.In my view,people waste water and never care about the shortage of pure water.Some people live in the area where with rich water resource,but they use the water as they want.Never think about that the pure water for use is not enough.In their mind,water is infinite.Besides,the government didn’t take enough actions to tell people that we should save water as possible as we can,and the method to save water.
