does wildlife need our management? (part 2)
Continuing Jenny Sue Hane's thought-provoking and biblically grounded post "Does Wildlife Need Our Management?" ...
There are already signs that “management” by humans might not be all it’s cracked up to be. Unlike natural predators, we are not limited in our choice of prey by our strength and speed. So although hunters might describe their work as “culling,” in reality they often take the highest quality animals they can find. Traits that once improved animals’ ability to survive are now working against them by making them desirable targets for hunters, so reproductive selection begins to reduce or eliminate those traits. Elephants without tusks have increased, kangaroos are getting smaller, and bighorn sheep are developing less impressive headgear. Our attempts to control nature may actually reduce the genetic strength and diversity of animal populations. Is this a sign of responsible stewardship in action? Is this what we wanted? (See for instance Newsweek's "It's Survival of the Weak and Scrawny.")
