If you are trying to do your bit for sustainability and save water by taking shorter showers, then a new report on sustainability reveals for the first time that there are more effective ways that our everyday choices can have a positive impact on the environment.
For example, the glass of juice you have for breakfast might have used the same amount of water in its production as the amount you have just saved by cutting your shower from 10 to 5 minutes. The milk on your cereal might have used even more.
Balancing Act, a world first that has been developed for the Australia economy by scientists from CSIRO (澳大利亚联邦科学月工业研究组织) and the University of Sydney, looks across 135 industry sectors of the Australian economy and quantifies the impacts and contributions across ten social, environmental, and financial indicators.
Report co-author CSIRO scientist, Barney Foran, says that sustainability for Australia is a balancing act as we try to make decisions and trade-offs in the face of often-competing economic, social and environmental attributes.
"We still need to eat and shower—and it is still worth taking shorter showers to save our stressed urban water supplies—but now consumers have a new tool to help us make more informed choices about different types of products based on a new sustainability rating," says Foran.
Different to other studies because of its detailed observation of the full production chain, this report is able to show the full effects--both direct and indirect of the production of an individual conunodity or serwce, cappuccinos( 卡布奇诺咖啡 )or haircuts. It highlights sustainability challenges for different industries and points out areas in the production chain where a focused effort would make a significant difference.
All effects are referenced back to a consumption dollar roughly the dollar spent by a consumer in everyday life. It also shows that each consumption dollar is quite different-some dollars are positive and create employment, or suck in imports or generate government revenue. Other consumption dollars are less positive through their high use of water or production of greenhouse gas emissions.
This relatively simple presentation of highly complex issues makes this a powerful tool for people who are interested in sustainability to move beyond decisions based on dollars and cents and enables them to make decisions based on a contribution to society, environment, and economy.

A.suggests that saving water by raking shorter showers is ineffective

62、 回答62-71题：
Marriage emerged as the most popular institution throughout history primarily because it was an effective arrangement to improve the care and upbringing of children. Marriage is not necessary to have children, but it has been of enormous importance in the rearing of children.
With the sharp declines in birth rates since 1970 in Western and other rich countries, including much larger fractions of adults who do not have any children, both men and women have significantly increased their ages marriage, and sharply raised their tendencies to divorce. In 1950, a typical woman and man married at ages 20.3 and 22.8 respectively, whereas now the typical marital ages are 26.0 and 27.7. These changes in age at mariage are related to reduced demand for many children, increased college education of both men and women but especially of women, much greater labor force participation of married and divorced women, and the narrowing of the gender gap in earnings.
The most important economic and social concerns due to low marriage rates are the effects on roaring of children. These effects are not due to lower marriage rates alone, but rather to the close connection between these low rates and high divorce rates, and to the greater tendency of women to have children without being married, or without living with the fathers of their children.
