While roaming in the zoo Stephan asked his grandfather, "What is the difference between a zoo and a sanctuary? "
In a zoo, people who come to visit can roam around as the way they like. However, in a sanctuary they have to follow certain rules and regulations because the animals are in their native habitat and should not be disturbed.
Zoo: Zoo is created as an artificial habitat for animals and birds. In a zoo, the animals and birds are held in captive. It is a place that is created by man with an intention to keep the birds and animals to be watched by visitors and people as a part of the tourism of a country. A zoo is open to general public with visiting timings.
Sanctuary: It is a natural habitat for animals and birds. In other words, a sanctuary is created by the animals and the birds on their own accord. In a sanctuary, the animals and birds are not held in captive but are free to roam and fly about as they want. Birds and animals take care of themselves and they look after their own living.
