We were sorry to hear of the fatal attack on a zookeeper at Kolmarden's wolf exhibit in Sweden (News, June 17). The tragedy is just one of a series of preventable incidents in which people have been injured by captive animals.
Denying wild animals the opportunity to fulfil their most basic instincts, such as selecting a mate and leading a life without human domination, can lead to neurotic behaviour and depression. To detain a pack of eight wolves, who would ordinarily establish a territory of many miles, in a limited space can only aggravate them.
The money spent on zoos would be far better spent on programmes to protect wildlife populations in their natural habitats. That is the ultimate salvation for endangered species.
