“The world was becoming a zoo, without cages.”
“A world without huge regions of total wilderness would be a cage; a world without lions and tigers and vultures and snakes and elk and bison would be - will be - a human zoo. A high-tech slum.”
“The caged eagle become a metaphor for all forms of isolation, the ultimate in imprisonment. A zoo is prison.”
“Zoos are full, prisons are overflowing. Ah, my. How the world still dearly loves a cage.”
“My mind is like a Zoo with no cages... Watch where you step”
“In zoos, along with the animals, the humanity of man is also prisoned! No cage is humane!”
