I was not born when the Lassie series starting in 1954. The only episodes saw Lassie was from 1964 to 1968 when she was owned by the U.S. Forest Ranger Corey Stuart. I was sad when Corey Stuart was severely injure while fighting a forest fire and his character was taken out of the series. One of Lassie's episode was a guy dumping out all his garbage into a river and the guy with Lassie's help save a raccoon whose head was stuck in a tin can which was part of the man's garbage. The man look at the river and saw how he had despoil the river's beauty with his trash plus nearly causing an animal to die from it. He went back down the river to remove all the garbage. It show how we should protect, respect, and cherish nature and not treat it like a huge dumping ground for all our garbage. That is why we have agencies like Fish and Game and the Forest Service to protect the land from human misconduct.
