Because The Black Buck and other such species that live there are Endangered we hardly have any Wildlife in Chennai so leave what's left of it. I dont think that its fine if  the PCCF agrees that its okay to build buildings around the wildlife park, citizens should have an opinion on this too as it is ours and im sure you can build an IIT building somewhere else.People enjoy the park Why take that Happiness away from everybody? .There should be an Eco-sensitive zone around it.
