Divorce bad for the environment, researchers say
Married households use resources more efficiently than divorced households: author
Soaring divorce rates around the globe are taking a toll on the environment, American researchers suggested in a study released Monday.
Michigan State University researcher Jianguo "Jack" Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy.They said housing units require space, construction materials and fuel to heat and cool, regardless of the number of inhabitants.
For example, in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water. An additional 38 million extra rooms required heating and lighting that same yeardue to divorced households.
That costs $6.9 billion USin extra utility costs per year, Liusaid, plus an added $3.6 billion for water, in addition to other costs such as land use.
"A married household actually uses resources more efficiently than a divorced household," Liu said. He said that in cohabitating households, people will watch the same television, share the air conditioning and heat and use the same refrigerator, all things that use energy at a regularly stable rate regardless of the number of uses.
Liu said he was not condemning divorce, "Some people really need to get divorces." He said cohabitation — whether by a family, friends or even in a commune — was simply a more environmentally friendly option. Additionally, the researchers noted that trends other than divorce are also changing family living structures, such as the end of multiple generations of a family sharing a home and people remaining single longer.
"People's first reaction to this research is surprise, and then it seems simple," Liu said in a release. "But a lot of things become simple after research is done. Our challenges were to connect the dots and quantify their relationships. People have been talking about how to protect the environment and combat climate change, but divorce is an overlooked factor that needs to be considered."
He saidthe increasing energy demands caused by divorce should beconsidered by governments when they arecreating environmental policies.
The research waspublished in this week'sonline edition of the Proceedings of the National Academy of Sciences.
