Have you ever wondered how much trash you produce in a day? How about a whole lunchroom of elementary school students? Nanette Heffernan, author of the newly-published children’s book Earth Hour: A Lights-Out Event for Our Planet, became curious about this question while working as a lunchroom volunteer at her children’s elementary school about a decade ago. She conducted a trash audit, meticulously counting every chip and plastic bag in the trash for a week. 

“I told the principal, if you support waste-free lunch, I’ll do it for another week, and I’ll make a hat,” said Heffernan. Within the first day, the hat was complete, and it quickly grew into a suit because there was just so much trash. 

For Heffernan, what started out as a somewhat facetious challenge, soon morphed into an iconic and highly-impactful visual reminder of the astonishing amount of waste produced by school lunches every day. Ten years later, Heffernan continues to don her trash suit at school assemblies, festivals, and other educational events to draw attention to the environmental impact of single-use disposables. “Your first breath you laugh, then you pause, and then you react,” she said. 

Educating children (and “their grown-ups,” as Heffernan likes to say) about how to reduce waste is just one part of Heffernan’s work as a sustainability consultant. Her new book, Earth Hour, aims to reach an even wider audience of children who are looking for ways to get involved in protecting the planet. Earth Hour is a global environmental movement sponsored by the World Wildlife Fund. This year, Earth Hour takes place on Saturday, March 28. Wherever you are on the planet, at 8:30pm on March 28, you shut your lights off for the hour as a pledge of what you’re going to do for the environment for the rest of the year. “It’s not about how much energy you save in that hour,” says Heffernan. She likens the event to Valentine’s Day. “We love each other year-round, but we go out of our way to show it on Valentine’s Day. It’s the same for Earth Hour.” 

Heffernan emphasizes that participating in Earth Hour is a way for people of all ages to get involved in a tangible way. “Kids have so many rules,” says Heffernan, noting that children are often told they have to go to bed at a certain time, eat their vegetables, do their homework, and more. “It’s easy for a child to feel overwhelmed when you hear these stories about climate change. They think, ‘What can I do, I’m only 7?’  You can participate [in Earth Hour] when you’re 7, and you don’t need permission.”

Above all, Heffernan hopes that her book inspires optimism. “[Kids] have so much power in their little hands to make a difference. With that finger they can turn off the light, with that hand they can turn off the water, they can say ‘no thank you’ to single-use plastic. Whatever their pledge is, it makes a huge impact,” said Heffernan. 

Earth Hour: A Lights-Out Event for Our Planet is available from Charlesbridge Publishing at most independent local bookstores, as well as some Barnes & Noble stores.
