it sucks (IMHO) to see people collecting like that.
I used to collect a lot, when I was younger and didn't know any better. Now I'm happy to take only pictures. The pleasure is in seeing the animals in the wild. Yes, I collect a few animals, maybe in the range of a 2 or 3 per year. I feel that is sustainable harvest for the animals I collect. But then again, if EVERYONE did the same, maybe that small number is even too much.
I certainly understand the point he is trying to make, but maybe he is making it from the wrong side of the fence (IMO).
