One of the most widly discussed probles is the following, if zoos should exist at all and if it’s goot to keep animals in captivity. This problem is being discussed in Europe and in USA than in Russia.
Nowadays there are a lot of debates in mass-media. On the one hand critics say that zoos shouldn’t exist at all because they imprison animals. Animals in zoos are deprived of the natural environment and they are in the wild. In critic’s opinion it’s cruel to keep animals in captivity a special in tiny cages and squalid conditions.
On the other hand the re are some opinions in defence of zoos. Firstly, it’s good entertaiment. In zoos we can experious to animals at close quartiers. Zoos have educationally and scientifically value. They protect rare specious from disappearing. Many rare specious are bred in zoos and then relised in the wild. In defence of zoos we can say that they are different. On the one hand there are roadside menageries crammed with tiny cage where animals are kept in squalid conditions.
On the other hand there are such establishments like London or Berlin zoos with some-million-dollar a year budget, big stuff and conservation projects all of the world. While critising zoos protesters make usually mistakes. Very often their perception is based on ignorance.
Nature films often show peaceful settings of animals and hardly ever the darker side of life in the wild. For example, the lingering deaths from deseases, starvation or inept predators.
One more common mistake made by critics is that they believe that there are large arious when animals can live naturally, are defected by human. Bur the reality is far from it. Rain forests, being a natural environment of many specious are disappearing very fast. Many areas specious just have no where to live. That’s why they are at the age of extinction.
Safary parks could be good alternative to zoos. Because it’s people who are in cages while animals move freely about, but the freedom is the quite false. Because the animals are often rounded up forced back into the open. So the visitors could get their moneys worth. Many safary-parks are commercialized very much. And the get-rich-quick philosophy dominated there.
I think that zoos should exist, because they have educationally value for example for our children. They can see there some animals, which we can see only on TV or in encyclopedies.

Заранее спасибо!

Такое отношение к делу заслуживает не просто критики, оно заслуживает "пинков" - например, "неуда".
