In 1995, the US Fish and Wildlife Service, along with Canadian biologists, captured 14 wolves in Canada and placed them in Yellowstone National Park, where they had been extinct since 1926.
Over the next few years, the number of wolves rose, but that was the least of the changes that took place in Yellowstone…
The effects were more striking than anyone could have expected.
The entire ecosystem of the national park transformed and it went so far that even the rivers changed! How could this have happened?
Watch the video and marvel at the amazing way in which nature works!

1995, US Fish and Wildlife Service zajedno sa kanadskim biolozima zarobili su 14 vukova u Kanadi i pustili ih u Jelouston nacionalni park odakle su prethodno istrebljeni još od 1926. godine.
U nekoliko narednih godina, broj vukova u Jeloustonu je rastao, ali to nije bila najveća promena koja je zadesila ovaj nacionalni park.
Efekat je bio krajnje neočekivan. Čitav ekosistem se promenio tako da je to uticalo i na reke koje su se, takođe promenile. U video snimku iznad, možete videti kako
