Abstract
However dangerous or even tragic anthropogenic phenomena might be for living nature, Man is able to restore the population of species which are on the brink of extinction. The examples are many, exceeding by far those usually referred to by specialists. Some are included in Table 11.1, which convincingly shows that the population of species is restored if Man takes special and active measures. This process often occurs in countries with the highest population density. Over the second half of the 20th century, in Britain, for example, there has been a steady growth of the population of some species, such as the wild cat (Felis silvestris), the polecat (Mustela putorius) and the marten (Martes martes). In 1984, the United States excluded the brown pelican (Pelicanus occidentalis) and the American alligator (Alligator mississipiensis) from the list of rare species thanks to successful measures to restore their population. There are examples, albeit rare, of the restoration of the population of a species whose numbers have dropped under the pressure of excessive hunting or fishing, without banning such activities altogether (though strict regulations measures were, of course, adopted). This is the case with the Pacific herring (Clupea harengus pallasi) in the north-western part of the Sea of Okhotsk, the king crab (Paralithodes camtschatica), the pollock (Theragra chalcogramma), some seals and a number of other species (Table 11.1). As a result of restoration, ten species and subspecies of mammals and birds have been transferred from the red to the green pages of the International Red Book.
