Wolves help Yellowstone Through Trophic Cascade

Nothing stirs up controversy like wolves.  In the western part of the United States where I live, their reintroduction was met with stiff resistance.  A few of the wolves released have been found dead, their bodies full of bullets. Unfortunately, the shooters may not fully understand that wolves and other predators are essential for the environment. Besides culling the weak, wolves change the behavior of their prey unleashing a myriad of effects. Through the ‘trophic cascade’, the wolves released into Yellowstone have actually affected rivers.  Please watch this amazing video titled, “How Wolves Change Rivers” to learn more.
