Today is World Wildlife Day.
I want to share three keystone species—animals with an extraordinary role in keeping ecosystems balanced—and why they matter to all of us:
Elephants.
Bears.
Wolves.
These ancient species have lived on Earth for millions of years—long before cities, roads, or development.
Elephants have walked this planet for approximately 60 million years.
Bears have been here for about 55 million years.
Wolves for roughly 4–5 million years.
Each is part of nature’s long story.
Elephants are known as the gardeners of the forest. As they move across landscapes, they disperse seeds, open clearings, and create space for forests to regenerate. Entire ecosystems grow because elephants walk.
Bears shape the land in similar ways. As they forage, they spread seeds and nutrients across vast areas, strengthening forests and supporting biodiversity. Their presence increases resilience within the ecosystems they inhabit.
And wolves?
When wolves were reintroduced to Yellowstone National Park in 1996, something extraordinary happened.
Elk changed their grazing patterns.
Vegetation recovered.
Beavers returned.
Wetlands stabilized.
Bird populations increased.
Even river systems shifted.
That is the power of a keystone species.
For millions of years, these animals have shaped the natural world. Life is deeply interconnected. Remove one piece, and the system changes.
Today, both the grizzly bear and gray wolf face renewed threats to their protections under the Endangered Species Act.
The Endangered Species Act exists to:
• Prevent extinction
• Support species recovery
• Safeguard the ecosystems wildlife depend on
And it works. More than 99% of species listed under it have avoided extinction.
When we protect wildlife, we protect the living systems that sustain us.
Deep down, we know we depend on nature. Yet we often live as if we are separate from it.
Nature is not optional. It has cared for us—quietly and consistently.
The question is no longer whether nature matters.
The question is whether we will remember that we belong to it.
Wildlife is not separate from us. They are a part of the intricate web of life that sustains us.
Protecting wildlife is protecting ourselves.
Please take a moment to call your federal legislators and ask them to protect grizzly bears and wolves by keeping them under the Endangered Species Act. You can find your representatives at usa.gov/elected-officials.
