" It isn't insane." Dane Blumstaine, a behavior  conservation biologist at UCLA." Now member, Some of these might local parks, but you know a lot of people are going and seeking out natural areas annually around the world, and therefore the potential impact of this can be quite large."   And the potential impact, to put it bluntly, " You know, does ecotourism make animals dumb?" Or in other words, could our presence disrupt and change the instincts of wild animals and ultimately affect their survival? Blumstaine and his colleagues surveyed literature on human-wildlife interactions all over the world from chimpanzee ecotourism in Uganda to ? and they concluded that human tourism, no matter how well-intentioned, might desensitize animals, making them easier preys for poachers and predators. Now a couple of mechanism might be at play. There is what's called the human shield effect. Predators are less likely to pounce when humans are around, making preys less vigilant even after we leave. Or we simple habitually played a large noisy animals,like us. And thus render a more susceptible depredators later.

  So, yeah, it does seem we may be inadvertently or advertently domesticating life through tourism and wildlife tourism and eco-tourism.

  The reveal is in the journal " Trans in ecology and evolution." Now this paper isn't a direct proof that tourism actually desensitize animals. It's just a theory at this point.

  What we have is we have all of the pieces of puzzle sort of lining up and we are  a pathway by which this could be an issue. Is it and under what conditions? We don't know and our paper  really is rallying five or four more researches on the topic. Research which will hopefully give land managers the tool they need to convince our humans not to let the world wildlife to death.
