Movies like Chicken Run and Bolt encourage young children to have respect and compassion for animals; later, these same children are taught that in the "Real World," people eat animals all the time, and it's no big deal and nothing about which to get upset.
We all love watching heartwarming family films in which people motivated by greed or hatred lose and those who stay true to themselves and demonstrate kindness win. We actively seek these movies for our children; then, at some indeterminable point, varying from family to family, we slowly start to un-teach them. We train them to turn their empathy switches off and attempt to normalize for them the imprisonment, murder, and consumption of creatures we once inspired them to regard as friends.
Once upon a Forest (1993) is by far one of my favorite children's movies of all time. My mother rented it for me from the local public library when I was about six. It tells the story of the Furlings, a gaggle of woodland critters-a hedgehog, a raccoon, a mouse, and so forth-and their wise teacher, Cornelius the Badger. Humans-known to the critters as Shoemans due to their limited perspective from the ground of humans as large, rubber boots-are responsible for the release of poisoned gas into the forest. A driver throws a glass bottle out of his window, which breaks, causing the tires of his gas-filled truck to pop and ultimately overturning the truck. Michelle, Cornelius's granddaughter, inhales some of the leaking gas and becomes gravely ill. It falls to the Furlings to retrieve medicinal plants for her in a far-off region of the forest.
