Thank you for all your comments. It's interesting to see how people view nature and modern nature photography. Most of us seem to be ok with how photographers take their photos (including Photoshop), as long as the photograping hoards are not anywhere near us.
It seems that majority of us also try to educate people through our photography, but share the concern of humanity's ongoing ignorance and lack of concern when it comes to nature.
As for sharing our pictures, yes I agree, someone using a personal picture of me for commercial purposes without my consent is not on. My general nature pictures might be ok, but not personal ones.
There are a couple of other environmental issues I'm interested in getting people's views on, so hopefully I'll post those soon.
