问题     It’s time to be water efficient!
    As populations increase across Australia and the rest of the world, demand for water will also increase. If we don’t reduce each individual’s demand for water (both directly and through embodied water) , the water situation will become dire.
    It is obvious that we cannot increase demands for water much more without detrimental (有害的) effects to the environment, society and the economy.
    It’s all too easy to blame someone else for the water situation— if 70% of water is used for agriculture then that’s what we should target —but it’s not that easy. We all depend on the food and resources that agriculture provides, and while there are definitely opportunities to increase water efficiency on the farm, the solution will take more than that.
    We each share responsibility for the sustainable management of our water resources, which means using less water at home, in the workplace, at school, on holidays, on the farm, . . . everyone, everywhere, every time.
    It’s time to become water efficient! This involves reassessing our relationship with water, and learning to use it more sparingly. On the most basic level, it requires a behavioral change, and assigning a value to water that truly reflects its worth.
    We can also unlock economic benefits of being water efficient. There are many real world exampies given in the case studies on this site.
    Everybody has a responsibility to save water, if future generations are to enjoy a similar standard of living to the one we enjoy now. In fact, many of the impacts associated with water use are likely to have an effect on our own lives!
