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 behavioural（行动的） 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 examples 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!

I grew up poor---living in the housing projects (住房) with six brothers, three sisters, a varying assortment (各式各样东西的混合) of foster kids (养子), my father, and a wonderful mother, Scarlette Hunley. We had little money and few worldly goods, but plenty of love and attention. I was  36  and energetic. I understood that no matter how poor a person was, he could still  37  a dream.

My dream was  38 . By the time I was sixteen, I could crush a baseball, and hit anything that moved on the baseball field. I was also  39 : My high school coach Jarvis, who not only believed in me, but taught me how to believe in myself. He  40  me the difference between having a dream and showing conviction (信念). One particular incident with Coach Jarvis changed my life forever.

It was the summer between my junior and senior years, and a friend  41  me for a summer job. This meant a chance for money in my pocket—cash for dates with girls, certainly, money for a new bike and new clothes, and the  42  of savings for a house for my mother. The prospect of a summer job was attractive and interesting, and I wanted to jump at the opportunity. Then I realized I would have to  43  summer baseball to handle the work schedule, and that meant I would have to tell Coach Jarvis I wouldn’t be playing.

When I told Coach Jarvis, he was  44  as I expected him to be. “You have your whole life to work，” he said. “Your  45  days are limited. You can’t afford to waste them.”

I stood before him with my head hanging, trying to think of the words that would explain to him why my dream of buying my mom a house and having money in my pocket was worth facing his  46  to me.

“How much are you going to make at this job, son?” He demanded.

“3.5 dollars an hour.” I replied.

“Well,” he asked, “Is $3.5 an hour the price of a dream?”

That question, the plainness of it, laid bare for me the difference between wanting something right now and having a goal. I delicated myself to sports that summer and with the year I was hired by the Pittsburgh Pirates to play baseball, and was  47  a $20,000 contract. I signed with the Denver Broncos in 1998 for $1.7 million, and bought my mother the house of my dreams.
