Am I the only one who feels many of the enclosures...

Am I the only one who feels many of the enclosures are to small? I remember having gone to the Toronto zoo years past and the enclosures being much larger. I appreciate the need to educate the public and have them care about animals in order to effect positive change. But it still feels as if some of the animals are being served in ways which cause them a lot of stress. The zoo itself is beautiful and well kept, and the activities and attractions are plentiful. The cost is high, but merited..
