“They’re on my case about getting a hybrid car. They want me to replace all the light bulbs in the house with energy-saving bulbs.”
In Clinton Hill, Brooklyn, Jan Schmidt, a stay-at-home mother, and Mark Goetz, a professor of furniture design, have watched, amazed, as their 4-year-old son chastises them for letting the water run while they brush their teeth. “He’ll come over and turn it off and say, ‘Every day is Earth Day,’ ” Ms. Schmidt said. “He learned it at school.”
“They’ll say, ‘Mom, I thought we weren’t supposed to use plastic bags,’ ” she said. Douglas and Alison Distefano, of Rumson, N.J., who have two children, dubbed their fifth grader, Olivia, “the recycling militant general.”
Paul Wyckoff, a writer in Hunterdon County, N.J., said his 15-year-old son, Will, yells at him for “leaving the car idling for a few seconds in the driveway.” He has even taken to turning off nightlights to save energy. “My philosophy is get the big stuff,” Mr. Wyckoff said. “I think he takes it too far. But I’m proud of him. I think he’ll moderate with age.”
