You're never too young to make a difference, and a group of fifth graders in Park Slope is doing just that with a brand-new book.

For 11-year-old Isobel Levenson, she says she knows a thing or two about conserving wildlife.

“We need to protect the wildlife right now more than ever, with all these poachers out there killing these poor animals that just want to eat food and live their lives,” says Levenson.

She was one of many fifth grade students at P.S. 107, taking part in an annual initiative her mom created seven years ago.

“Beast Relief has been both to, educate the kids at P.S 107 about the wonders of animals, and also take concrete steps to protect and help those animals,” says Katherine Eban, Isobel’s mother.

After students learn, they write about an endangered animal. This year, students wrote their own book “One Special Lion.”

“It's about this one lion, Sion, and it's about her struggles, how she grew, and she got better to be this one great lion,” says Levenson.

All the proceeds from the book support lion conservation work in Tanzania.

Edwin Tambara spearheads those efforts at the African Wildlife Foundation, and he says the work of these young people is needed.

“They actually hold the power that if they drive this message, it pushes those in leadership to consider things that are important to young people,” says Tambara, of the African Wildlife Foundation.

Levenson says she is happy to help.

“Even though it's just one animal, it's still one animal, that can go a long way,”says Levenson.
