Its effects are neuroligical shut down, blindness, closing of the esophugus, and thats what happens before death so its slow and very painful and very contagious. The only remedy is mass dispatching of entire herds in a big area.
I am not too familiar with CWD, but its an infection of one kind or another.

So because these animals die from CWD, we're better off shooting them? I don't get how our encorachment into their habitat influences CWD. I guess stressing the animal increases risk of disease, so why not stop stressing the animal?

As human growth expands the natural food sources for the animals get smaller therefore you have issues as starvation, poor health etc that leads to disease...

If we let the wildlife over populate and dont keep them in check it is worse for the wildlife. Now thats just with deer. The same issues hold true with any species of wildlife where they are abundant.
So we humans encroach into an animals range, and strip it of food and cover, so it gets deathly ill and our solution is to shoot the animal? Seems like we would have been better off shooting it before it had a chance to get sick. Or why not change our ways so as to prevent the animals from losing natural food sources and habitat?

What happened to the natural pretadors of deer in Texas? I know in the midwest, humans killed them off, either via gun or by converting forest into hyperfertilized corn field.

When I was in college, the same rhetoric was being used. The deer are over populated, the gators are over populated, etc etc. The solution, kill them. Lots of fish and game people still believe it because that was what they were taught. Hell, I was taught that forests have a climax stage of succession. But it seems like a farily new paradigm is emerging that doesn't agree with these ideas. The overpopulation of a species is probably at the making of our own hands. Our notion that any species is overpopulated might be flawed. Would we have said the passanger pigeon was overpopulated?

I guess my point is still it becomes a question of values. We don't want to see starving deer so we cull the herd, no matter how natural CWD might be. We don't want gators in our yard, so we shoot them or move them. It is humans who always prevail because of the systems we've instituted. We displace animals and people who don't own land. We value our private property over animals. It's the same reason we kill moles. I only want the good nature in my yard, you know butterflies, flowers, and birds.

I'm not saying you personally think this, but many people do. Again, the lady from Billy the Exterminator - and she was angry about a harmless armadillo.
