Wilder protected areas get eight billion visitors a year, and that's just on land. Underwater reserves? add a million to the tally1, which, considering these are protected areas, seems like an insane number of people.
" 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 annually2 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 preys3 for poachers and predators4. Now a couple of mechanism5 might be at play. There is what's called the human shield effect. Predators are less likely to pounce6 when humans are around, making preys less vigilant7 even after we leave. Or we simple habitually8 played a large noisy animals,like us. And thus render a more susceptible9 depredators later.
So, yeah, it does seem we may be inadvertently or advertently domesticating10 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 lining11 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.
