(If what I just wrote makes you sad or angry,
I've been working for sevral years now on the reestablishment of the American Chestnut tree.
We plant seedlings and they are like deer magnets. They will be sheared off to the ground and other species adjacent are untouched.
I travel a great deal in East Tennessee, South West Virginia and Western North Carolina. I see many farms in the process of reverting to woodland. These are in all stages from pastures over grown with blackberrite, to cedar forests and the climax hard wood saplings. There is no old growth and climax is is wood lots that vary in age but are not old.
It is these woodlands that are growing large deer and turkey populations.
While I know very well that human beings (at least most of us) rank above the lower animal species, we have displaced so many animals with our housing projects, for example. Then we freak out if we see them on OUR property. Do you know what I mean?
This may have nothing to do with the growth of the deer population, but they do cross busy highways to get from one "forest" area to another.
Killing them for the fun of it bothers me; I get no joy from killing anything, even a plant.
Oops. I confess. My position regarding insects is that they have no rights to live in my house. I will exterminate them, just as I will smack a mosquito dead when it lands on my skin.
Zapping a mosquito, a yellow jacket, or a wasp occurs without second thougts. Killing SOME insects causes momentary sorrow.
