 SYDNEY, Australia (AP) - From the street, Alicia Campbell's house looks no different from the others in her suburban cul-de-sac. But it has a secret: It's green — very green.
The four-bedroom home she shares with husband Jason Young and their two sons sucks no water from Australia's drought-stricken reservoirs, recycles everything from food scraps to sewage, and even pumps electricity back into Sydney's power grid.
As the world debates how best to respond to climate change, families such as Campbell's, like others in the U.S. and Europe, are taking the challenge personally.
