Many would argue that the most humane way to let them die is to let nature take its course and to let them return to the earth while we all eat tofu and sing Kum Ba Ya.
Yes, but they'd be wrong.
I know what you're saying, I guess I don't see it as being negative so much as being honest.
Bowhunting
is humane, but if we had to put our dog down and we had a choice between shooting it inthe head with a gun or shooting it in the chest with an arrow. (somebody already brought something like this up) Most all of us would chose the bullet in the brain. That's a long way from secretly thinking our archery equipment is inhumane. That's all I'm saying.
But enough this talk of cow shooting, it's making me hungry. (by the way you can hunt wild cows and horses in Australia)
I'm off to wrestle with my lawn mower some more...
