Yes - people who destroy habitat annoy me.
An interesting note - as a wee kid (5 to 10) there were thousands of western toads in the community I live in. They were everywhere. Their numbers started to dwindle, and soon I found none. When I was 16 - suddenly there were thousands again - as if a plague from Egypt had happened.
I can't explain it - but the ponds where they use to be only had treefrogs for several years, at least that I could find, and then suddenly a few years later they were everywhere again.
I think due to el niño, or whatever else, there are cycles for which a species is extremely prolific and cycles when you just think they are completely gone - but they're not, they just aren't out.
With the toads, maybe changes in the water table?
I personally believe the reduction of the red legged frog is a primary cause for the reduction of the giant garter snake in California - Bullfrogs grow rapidly and are soon big enough that they do not make good prey, as well as making excellent predators for the baby snakes.
I think it is easy to blame collectors and completely miss the real cause.
