Animals have long been used for the entertainment and education of humans. Zoos, aquariums and circuses showcase some of the many creatures that share our planet, but these environments often do not meet the physical, social, behavioral or emotional conditions necessary for the animals to thrive. Circuses in particular have come under fire for employing tactics of intimidation and physical brutality to teach animals routines. Recently, countries like Sweden, Costa Rica, Austria, Finland, India and Singapore have come forward to ban or restrict the use of animals in circuses. The use of animals in filmmaking has also received criticism for allegedly harmful and sometimes lethal treatment of animals during production. Meanwhile, proponents believe that zoos, circuses and aquariums are essential in building awareness of animal welfare.
