The situation was already alarming, since, when vegetation is lost, other animals, such as Grizzlies bears, become extinct, without mentioning the entire natural environment, so the introduction of wolves began in 1995 in the Park of Yellowstone, and the result has been simply marvelous.

The presence of these natural predators par excellence has meant that the so-called waterfall or trophic network was restarted.We are sure you know what it is, it is that succession of phenomena in which some, serve as food to others to create an ecosystem in balance io .Obviously, we know what that implies, that the wolves eat the moose, for example, the rabbits...However, the simple fact that the number of these last animals goes down implies that there is a lot more vegetation and, consequently, that the miracle work again.
