A helicopter crew from Brazilian news outlet Globo was in the skies over Sao Paulo when they encountered a rather surprising scene taking place. There, along the concrete banks of an urban river, a solitary black dog was spotted single-pawedily clearing the waterway of floating plastic debris.

And, from the looks it, he was having a blast doing it.

For some 20 minutes while the cameras rolled, the cleanly canine leapt and pounced at improperly-discarded plastic bottles, dutifully carrying them back to the shore.


All told, the news crew counted 25 bottles salvaged from the river, thanks to the dog.
