Power in Numbers

Biodiversity is God’s way of saying that every life matters and has a purpose. From the tiniest insect to the tallest tree, the vast variety of life on Earth reflects a deep, intricate design. Each species plays a role in the larger harmony of creation. Just as a symphony needs every instrument, ecosystems thrive when all their parts are present and working together. In this light, protecting biodiversity isn’t just science or stewardship—it’s an act of reverence. It’s our way of honoring creation by caring for the masterpiece we’ve been entrusted with.

Biodiversity—the variety of life in all its forms—is essential for healthy ecosystems. It provides humans with food, clean water, medicine, and climate stability. Diverse ecosystems are more resilient to environmental changes and threats like disease or natural disasters.

However, due to habitat loss, habitat fragmentation, pollution, invasive species, climate change, and overexploitation, biodiversity is declining at an alarming rate globally.

The reduction of biodiversity can destabilize ecosystems, reduce ecosystem services, and lead to economic and human health consequences. The effects are often cascading, meaning the loss of one species can disrupt many others.

Here in Ohio, we have 132 endangered species with 224 that are closely being monitored. A few examples of endangered species include the Indiana bat, Northern long-eared bat, Timber rattlesnake, and Eastern hellbender.

Keystone species give insight to the monumental impact biodiversity has on ecosystems. A keystone species is one whose impact on its ecosystem is disproportionately large relative to its abundance. When these species are removed or reintroduced, they can significantly reshape the entire environment.

Throughout history, we’ve fought to pull species back from the brink—and few stories are as powerful as the comeback of the bald eagle, once nearly gone, now soaring again as a symbol of successful conservation. Once nearly extinct in the lower 48 states due to DDT pesticide use and habitat loss, the bald eagle is now a conservation triumph. Banned pesticides, habitat protection, and breeding programs helped eagle populations rebound. In 2007, the bald eagle was removed from the U.S. Endangered Species List. In Ohio, their nests have increased dramatically—from just four known nests in 1979 to over 700 today.

Let’s keep driving species comeback by planting native species, creating water sources, reducing pesticide use, and supporting local conservation efforts. Engaging the community and educating others about biodiversity are also crucial for long-term success.
