In Catania, Italy, a teacher and her students are learning all about 350 – and growing new solutions!

Marina and her class spent Friday, the last day of the school week, learning all about the environment and 350ppm – and planting trees in the school grounds.

Every student also took home a little pot plant to plant in their backyard today – and on Tuesday they're going to share the stories with the school!

Have a look at some absolutely adorable photos here –
