Bears are timid in nature, and so will attack any people who approach them unexpectedly.

The most important thing you can do to prevent being attacked is to not approach them, so that they do not become surprised.

Brown Bear-seeeeenpaaaaaaai!

Good morning!

Hywah!?!

Wh-what do you want!?

Another aspect of bears is that they are omnivores, and do not eat just meat, but also berries and fruits and the like.

Mmmmmmmm, it's so sweet!

It's dangerous if they become aware of your presence, so you should observe them from a safe location.
