In May, Yellowstone National Park killed a newborn bison in the US state of Wyoming after a visitor touched the animal.
A man approached the newborn bison after the calf had been separated from its herd while trying to cross the Lamar River.
As the calf struggled, the man pushed the calf up from the river and onto the roadway.
The visitor was trying to help the calf rejoin its herd after it got separated from its mother, according to the park.
However, interference by people can cause a herd to reject its offspring.
The herd rejected the calf despite repeated attempts by park rangers to reunite the young bison.
The Park had no choice but to kill the young bison.
The road to hell is paved with good intentions.
