Wildlife in Yellowstone

I'd like to talk about wildlife in Yellowstone.
Yellowstone National Park was the world's first National Park. It is as large as half of Shikoku Island and famous for more than 300 geysers.
There are also many wild animals.

The ecosystem is preserved by park rangers there. You have to obey park regulations there. Feeding and approaching wildlife are prohibited.
Once, fed animals attacked people while searching for more food.
Since then, people have stopped feeding wild animals.

Wildlife have their own life and habits. I've realized that not disturbing their territory will be good for us in the end.  It is our responsibility
