EDUCATING OUR YOUTH

“Green schools connect children

to the real world in

unimaginable ways.

They inspire kids to want to

read and do math and learn, so

they can protect what they love

– the oceans, the forests and

wetlands, their friends and

families.

As parents and as communities,

we owe kids healthy, nurturing

environments that also teach

and inspire them.

That’s what green schools do.”
