Good writing! I have just visited the Manila zoo recently, and started researching this topic, as I was shocked by the condition the animals are kept there. For me, the zoo is usually a place I visit in every city I go to, and it is always a positive experience to see people/kids being educated about animals and the importance of protecting them, but none of that is happening in Manila. Quite the contrary actually, and it is saddening.
I strongly believe that publicity and awareness will help drive solution here, either by the zoo receiving more funds from the government, help from volunteers, or having the establishment privatized.
