Should Animals Be Kept In Zoos?

Is it ethical to keep animals in zoos?
London Zoological Gardens
First zoo in the world founded in 1828 for scientific study and then opened to the public in 1847.
Animals in zoos often lose their natural instincts because their habitat isn't natural.
Being kept in captivity doesn't allow animals to fully utilize their instincts, so many animals lose their natural behavior.
Even the first zoo did not have good living conditions for animals they kept.
Confinement overtime can lead to a disease called "zoochosis" where an animal acts abnormally, such as self-mutilation, over-grooming, pacing, swaying back and forth, or repetitive motion.
Sometimes, zoos keep their animals in bad living conditions.
As an alternative, exotic pets or animals injured in the wild should be kept and cared for at sancuaries or open range zoos.
Animal sanctuaries and open range zoos are places where an animal is brought to live and be protected for the rest of its life. They are larger and more natural than zoos.
Zoos are not ethical because they often do not give animals a good life.
Animals deserve more than a small exhibit, they deserve freedom.
