I totally agree with your opinion. Even though the initial purpose of zoo establishment might be humand oriented, nowadays zoos work as a shelter for animals who can't adjust in the 'changed- wild'. Zoo itself is not a bad place now but the problem exists in 'some' places and selifish peoples which must be regulated with strict law. Therefore I also believe that zoo should be kept but be changed in a way with stricter laws and more support from the government.
