Ever wondered if one species can have a significant impact on the ecosystem? What about if that species was to become extinct?

For the answers to questions above, check out the video below which shows the impact that the reintroduction of wolves into the Yellowstone National Park in the US has had on local biodiversity. The wolves remained absent from the park for over 70 years and in 1990s, when they were reintroduced in the area, they brought along a remarkable ‘Trophic Cascade‘.  Believe it or not, their presence even had an impact on the physical geography of the park. You need to check out the video below to see exactly how wolves have influenced the surroundings:

Reintroducing wolves to the park has helped curb the growth of the deer in the area, which has resulted in regeneration of vegetation and forests, helped reduce erosion and created more water pools, thereby resulting in a change of the course of the rivers all due to the response of the wolves. Birds, beavers and new amphibians have all returned to Yellowstone park.

The video above beautifully shows how one small change in the ecosystem can have a ripple effect on earth and life on it. For more information, you can check out the SustainableMan blog here.
