Within the confines of the boundaries of the park as a rule of thumb the animals should come first. Not man.
heya AjayB, we could have lots of fun here with this philosophy because it is such a hard one to get a good definition around, with almost everyone feeling differently about it, and feeling strongly about it too. (It is going off topic a bit so if a moddie wants to relocate it......)
Now I am not having a go at you or anyone, but just playing with the philosophy.... so no offence intended anywhere.
With the statement above, lets take that as accepted.
But, if we take roads - the effect of tar roads means that precipitation, rain, dew etc, tends to run off the road, due to the camber, onto the side of the road, resulting in increased lushness of of the grass there. This causes in turn, increased insect activity there, with resultant bird activity. Further, antelope tend to gather there in greater numbers. These occurrences are as a direct consequence of man's interference - if the road wasn't there - there would not be the unnatural congregations of life. A very unfortunate side effect is the numbers of insects, worms, birds and antelope etc. that get flattened by cars, some speeding, some travelling within limits. But dead the beasties are. Now, roads are out of the way areas, ... so to save the animals, the roads should be closed...
A daft example, but actually a VERY real one.
Then if we examine the consequences of some animals actions on other animals, because of original interference by man....
Take the birdhide. Man originally puts it in place, and lets assume that man has no more direct effect on animals.
Due to the hide being there, there is an unnatural sand patch underneath the hide, where the sun is shaded so grass does not grow. There is as a result an unnatural abundance of ant lions there, which cause unnatural levels of death, destruction, slaughter and mayhem amongst the ant population.....
At night, insectivores are attracted there due to the unnaturally high numbers of ant lions, in unnatural numbers, which results in a higher than usual number of fatalities from owls, caracals etc.
Man is not directly responsible, but indirectly, but ultimately still responsible due to his actions.
Ultimately, because we have started to interfere, we need to continue interfering. If we do not want to interfere at all, then we have to pull out completely. Even more unfortunately, as repulsive as it is - sometimes we have to interfere with innocent animals, even killing them at times.
So, if things are put on a scale - which is worse - forcibly removing a snake, possibly having to kill it, as it is in a hide, or the death of 10 000s of insects, hundreds of birds, dozens of mammals due to the roads.....
