MOUNT VERNON -- Life is full of hard truths and this little guy just learned one about littering.

Allie Hall says she picked her 6-year-old son up from school this week and he was distraught over the state of our environment.

Henry Marr apparently watched a video at school about pollution and was so upset he broke down in the car. Marr's mother caught his breakdown on camera and posted it on Facebook for family and friends, but then it blew up.

As of Friday afternoon, the video had 3 million views and later Friday evening that number approached 6 million. Hall says the environmentalist group Greenpeace shared the video. Buzzfeed also picked it up.

Marr is embracing his newfound fame.

"I think I'm going famous. I mean I'm on TV, I must be famous," said Marr.

Hall told KING5 that prior to seeing the video at school, Marr was passionate about the environment, but now he's on a whole other level.

"He's always been interested in the length of the shower I'm taking or saying daddy left the light on," said Hall.

Since Hall posted the video, Marr has since written a book entitled "Enjoy the Planet, Don't Wreck It."

He's also taken it upon himself to patrol his neighborhood park, Littler Mountain Park, as a 'park ranger.' He wears a vest and patrols the park, picking up litter and watching out for those not taking care of the earth. If he sees a "naughty person" he blows his whistle.

Marr also looks out for the welfare of animals. Friday evening Marr saved two slugs along a trail from being stepped on.

"I'm going to try to get the whole United States to clean the planet," said Marr.

When Marr grows up he wants to be a park ranger but first, he's hoping to be a guest on the talk show 'Ellen.'
