Can you fire at bear if it attacks you?
You should know that you can shoot pretty much any animal in self defense in the USA, including bears.
It is a normal reaction to get terrified when you are standing in front of a deadly fierce animal staring into your eyes. But, you must stay calm if you encounter a bear while rambling in a park. You should stop all your activities and evaluate the current situation.
And if you get too close to a bear, there are higher odds of getting attacked by it.
Do not fear or try to run away; the bear will chase you and down you down.
While attentively observing the actions of the bear, step back slowly in the opposite direction. Try not to scare a grizzly bear. In most cases, the bears flee away.
Prevent encountering a bear
Bears usually attack to deliver the fact that you are too close to them. The best way to avoid a bear attack is to prevent the ways that provoke a bear to attack you. First of all, keep a safe distance while enjoying the beautiful sight of a ferocious giant bear. In Yellowstone National Park, they provide the facility to witness the splendid spectacles of wildlife, especially bears, from your vehicles.
Other ways to prevent encountering a bear are as follows:
Stroll in groups rather than wandering alone.
Make noises while moving through the wild areas.
Stay alert and don’t get far in the wild areas.
Carry bear spray.
Do not feed them
