Answer
Zoos were created for human entertainment, yes, but that’s quickly becoming secondary in ones that have animal welfare at their heart – from those in Singapore and San Diego to London, Prague, Berlin and Al Ain. And the “cages” are no longer cramped, unsanitised prisons, but rather species-specific enclosures that keep in mind each animal’s need for space, greenery and water resources, with most even providing props and activities to keep the critters as entertained as its distant viewers.
As for education, do we really need to keep animals in captivity in order to learn about them or spark an interest? Hundreds of kids are still super-interested in dinosaurs or unicorns, despite the fact there are no cages offering an up-close look at these creatures.
We can conclude that both zoos and the wild have their own merits and demerits
