Too bad that National Academy of Science publications aren't 'pair reviewed'. Cause then we could make a good pundit case for tree-hugging being a family virtue
Seriously though: does this study infer the reverse, that marriage and childbearing while living in a McMansion reduce average resource consumption over the long term? Three divorced guys sharing an efficiency flat in the city? Course not.
The issue is with what's in the denominator. Unit of time? Square feet of living space/person? This kind of "science" we don't need - thank you very much.
A global trend of soaring divorce rates has led to a surge in the number of households with fewer people. The result: We collectively devour more space and gobble up more energy and water, say the authors of a new study published online this week in the Proceedings of the National Academy of Sciences.
"Not only the United States, but also other countries, including developing countries such as China and places with strict religious policies regarding divorce, are having more divorced households," said co-author Jianguo Liu of Michigan State University. "The consequent increases in consumption of water and energy and using more space are being seen everywhere."
