What's nice about new technology is it allows for opportunities to capture animal activity in remote natural environments, with minimal impact. For instance, the Katmai National Park "bear cam" in Brooks Falls, Alaska (where in season people watch grizzlies feed on salmon) is a rather popular webcam. Not only does the webcam reduce human impact, it equalizes: Brooks Falls is very remote, and thus it is very expensive to get there. The webcam brings a side of nature to everyone, that previously only the well-off would see.
I think zoos and aquariums can still exist, but moving to an animal hospital / research / protection model versus the entertainment model of Sea World and the like makes sense. I hope the environmental movement recognizes that the former is still valuable.
I disagree with the latter sentence. I think that seeing something in person -- whether an animal or a landscape -- is very different to seeing a photograph or video. That's why it's so different to travel somewhere to see something in person.
(Slightly off topic, but you'd be amazed at the wildlife that you come across in the highly urbanized parts of Vancouver because it is surrounded to the north and east by wilderness and has many rail corridors and parks that animals follow into the city.)
I think pictures have a much bigger impact on "moving" adults but zoos and aquariums have a greater overall impact for children (just my opinion).
What is the driving force behind moving animals to sanctuaries and protecting them? It's the love and care people have towards the animals and species, right? I'm not saying taking away zoos and aquariums are going to make humans cold blooded but I really think they help overall.
