Two tourists thought they were doing a good deed when in fact they were dooming an animal. The pair found a bison calf near a road in Yellowstone National Park and put it into their car so it would be warm. This act sealed the baby bison’s fate: it was no longer clear where it came from and which bison was its mother, meaning it couldn’t be reunited with its herd. What’s more, it started approaching people and cars on the road, creating dangerous situations. The bison had to be euthanized because two tourists couldn’t leave wildlife alone like they should have.
