Take a look at this amazing video showing how a species can have a huge impact on the entire ecosystem in which it lives, and even to change the geography of a region. – When wolves were reintroduced to Yellowstone National Park in the United States, while absent for almost 70 years, the most remarkable 'trophic transformation' occurred.

   The Human refusal to understand and accept the perfection of What really is the nature of this world that hosts it, will be the real reason he himself Kosmos will eliminate !And it wouldn't be the first time that the nature of this world will do !Video is a ray that illuminates the real side of the world That Is and shatters our Illusions of what we think the world is !

   Unlikely videos, and inconceivable until now, the,what only a few wolves would bring such changes to the environment and biodiversity of the National Park. Certainly functioned as counterweights, the balance of the ecosystem, but it is wonderful the size of change.
