The tulips and peonies have hit their early growth spurt. The grass is greening. Spring is here.

And it’s a time to reflect on ways to help the planet and the environment.

Green Newton has its annual Earth Day Festival on Sunday at Newton North High School. You can learn about the many eco-minded groups in Newton as well as different ways people are stepping up to fight climate change. And there will be electric vehicles on display for you to check out.

There are also a couple of concerts, a Nordic printmaking class and a popular movie about a hedgehog.
