Well, studies sure are helpful to have a better understanding of the behavior of animals and education is nice but at the end of the day, wild silver back gorilla’s won’t benefit a lot from the fact that a young boy in Cincinnati learnt something about their environment. Education should focus on areas close to where the species live for obvious reasons. Research is very interesting but it’s important to keep in mind that the fact of living in captivity makes a lot of changes in an animals behavior so studies are probably more relevant when the studied group lives in the wild.
I’m really sorry but Zoo’s are jails that allow us to look at animals. Just take a look at the size of any feline’s enclosure and how much territory they normally have and you’ll understand what we are doing to them.
