I think 3rd graders understand more than our adult “leaders.” For example, kids understand that adult “leaders” are destroying the planet they will inherit. Kids understand they must stop the adult so-called leaders who refuse to listen to the scientists. The kids know that they must act now if they want to have any chance of having a future.
Don’t write for adult leaders. They do not have the ability to comprehend reality. Write for children and inspire them to overthrow the climate abusers immediately.
