On the one hand, zoos can be educational especially for children who can see the animals they learn about at school. Furthermore zoos help increase the number of endangered species through controlled breeding programmes. Moreover, circus animals are loved by people of all ages, they get good treatmentand only perform for short periods.
On the other hand keeping animals in cages so the public can see them is unnecessary. For instance, there are a lot of documentaries that take away this need. In addition to this animals are forced to perform unnatural acts for the pleasure of people. Besides, with the new technology and special effects, there is no need to use live animals, as realistic models can be used instead.
In conclusion, animals should not be forced to perform diffrent acts when we have so many other alternatives
of entertainment and learning.
