Sure there are plenty of things that can kill you.
I hunt in the most concentrated poulation of grizzly bears in the lower forty eight. I have encountered them. Somebody in my group encounters one alomost every year. To ignore the possible threat would be foolish.
Any yet people ignore all varieties of possible threats with an alarming frequency, be them bears or simply not carrying sufficient water in the desert, but they do it and often find themselves in trouble and never seem to understand why it happened to them.
