The Athenian Agora. The Agora of Athens was the center of the ancient city: a large, open square where the citizens could assemble for a wide variety of purposes.

Bear spray is a non-lethal bear deterrent designed to stop aggressive behavior in bears. Its use can reduce human injuries caused by bears and the number of bears killed by people in self-defense.
Bear spray isn't unlike pepper spray that humans use to protect themselves from other humans. The main difference is that bear spray can shoot farther and casts a wider effective area. There are three main ingredients in bear spray: Oleoresin Capsicum (OC): oily residue from hot cayenne peppers. Capsicum is a naturally occurring ingredient that causes a burning sensation when sprayed in the face of an attacker.
