Times Colorado has grown since 1965
Since 1970, 73% of wildlife populations have disappeared, according to the World Wildlife Fund’s Living Planet Report 2024.
Freshwater wildlife populations have declined by 85%
Terrestrial wildlife populations by 69%
Marine wildlife populations by 56%
The main causes include habitat loss and degradation, hunting and fishing, followed by invasive species, disease, and climate change.
About 95% of the total biomass of all mammals on Earth’s surface is now composed of humans and their livestock.

We protect wildlife through science-based education that empowers the public and policymakers to advance ethical treatment of animals and promote resilient ecosystems through improved policies and statutes.

We envision a future of wildlife stewardship rooted in science, compassion, and thriving ecosystems.
"The tree which moves some to tears of joy is in the eyes of others only a green thing which stands in the way. Some see nature all ridicule and deformity, and by these I shall not regulate my propositions. And some see no nature at all. But to the eyes of the man of imagination, nature is imagination itself."
"Nature is the source of all true knowledge."
"Preserve and cherish the pale blue dot, the only home we've ever known."
"The earth laughs in flowers."
While Colorado’s human population has risen exponentially, habitat loss and other threats have harmed our state’s biodiversity. (Data from State of Colorado’s Biodiversity, 2011.)

“The eyes of the future are looking back at us, and they are praying for us to see beyond our own time. They are kneeling with hands clasped that we might act with restraint, that we might leave room for the life that is destined to come. To protect what is wild is to protect what is gentle. Perhaps the wilderness we fear is the pause between our own heartbeats, the silent space that says we live only by grace. Wilderness lives by this same grace. Wild mercy is in our hands.”
