The nostrils of an eagle are shaped exactly like the intakes of a jet plane. Regardless of the aerial velocity, over a hundred miles an hour, they can still breathe coming straight down for one thousand or ten thousand feet. They can see a ground squirrel for a mile, eight times beyond humans' eyes. Their talons are needle sharp. They separate the bones and the vertebrae and the minute they touch their quarry with that great foot, and they squeeze it down, it means that life is over.
Raptors only kill when they're hungry.
And they do not kill each other in fighting over sex or places to live. Gunpowder and the plow were the basic instruments used to change the environment to supply man's needs. When combined, many species of wildlife were doomed. A good example is the passenger pigeon. The problem is for the individual to understand the difference between the pursuit of happiness and its long range effect on our environment.
