NEW YORK (WABC) -- Some third graders in Brooklyn were being kind and writing letters at school this week.
They were called 'Love Letters to the Air'.
The students at PS 90 - The School for Environmental Studies and Community Wellness, gathered in the gym to write their letters on World Environment Day.
It was part of a project to promote positive change for the planet and help empower young people to influence policy solutions.
The letters are going to be presented to leaders at the United Nations Climate Summit in September.
If you see someone doing something extraordinarily kind, let us know at our "Be Kind" campaign page.
