Its time to be water efficient! As populations increase across Australia and the rest

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!

(答案→)D 解析：【小题1】文章后数第三段提到“在这个网站上有许多真实的世界研究案例”。【小题2】文章中间说到我们每个人都有责任节约用水，无论何时何地，要减少用水。【小题3】文章说到农业用水量大，没有办法减少，我们的食物要靠农业来提供；但并没有说农业用水在不断增加。【小题4】文章中两次提到 “It's time to be water efficient”也分析了节水的原因和重要性，又提供了可供参考的有价值的网站。

对的，就是这个意思
