What is the distinction between "sacred place" and "not in my backyard"?
The distinction appears to be that "sacred" applies to beliefs that were (at least allegedly) in existence before the people holding those beliefs were over run by a different culture that does not hold the same beliefs, but feels the need to show some respect to the culture that it conquered.
There will always be some people who would prefer to see things remain as they are. And, some will not like loosing access to places that they once held as "special" to their feeling of comfort.
Although nobody would respect my feelings as "sacred", I have watched the wild places that I used to visit as a child and young adult get bulldozed into unrecognizable condition and then covered with industries and seemingly endless tracts of suburban housing and strip malls. I definitely feel the loss. In my mind's eye, I can still see the previous conditions of these places that are no longer as they were. In one place, I can stand on a huge rock that was not moved, close my eyes and see the world of my youth spread out where it once was. But, then opening my eyes hurts my sense of well being and control of my own destiny.
So, I can relate. But, it ultimately comes down to a social and political decision. What do we set aside to remain as it has been in our memories and our ancestors' memories, and what do we allow others to change in the name of "progress". As human populations increase, and conflicts increase along with the population, we will have fewer and fewer places that will remain untouched.
