Yesterday, I found two videos from Sustainable Human about the importance of wolves and whales on the environment around them. One video talks about the reemergence of the wolf population in Yellowstone National Park and how the reintroduction of packs in 1995 helped to indirectly impact the course of the rivers in the park. The other video talks about the impact of whales on the climate, which is definitely something I never even thought about.

*Both videos do have close captioning for the narration.

For more information about wolves in Yellowstone National Park:

• National Park Service information about the wolves
• Wolves in Yellowstone National Park
• Gray Wolves Have Created a Balance between Predator and Prey

Also:

• Why whale poo could be the secret to reversing the effects of climate change

The thing that I really love about the videos is that they both highlight the fact that life and survival on Earth is all interconnected and an impact on one thing will usually have a domino effect on the surrounding species and environment.
