It doesn't matter whether they are important or not, or whether or not you consider them to be of value or a detriment. That is the beauty of a free society. Zoos, wildlife parks, museums, and other institutions are available for those who want to visit them, and in the free marketplace those who want to frequent and support them can and those who don't are free to stay away. I hate tattoo parlors and cigar bars, but others think they are great. Now maybe a cigar-smoking tattoo enthusiast will flame me for hating his or her favorite haunt, or maybe not. Who cares! It's still a (mostly) free country.
Articulate post...well written. Thanks
If the zoos are good for the animals, then not much of a problem...i like to see animals NOT caged...and soem zoos do that now, have them roam freer.
Circuses usually are not, but I will research more after reading another post.
