Yellow flowers in the grasslands of the Great Plains.

Grasslands are vast ecosystems that support biodiversity, provide critical support to global food systems, and play a major role in mitigating climate change. When grasslands like the Great Plains in the U.S. are lost or degraded, we lose benefits to humans and wildlife: https://wwf.to/3Q0I6zS

Baby dugong sighting! A rare wildlife sighting of a calf swimming alongside its parents in Indonesia’s central Alor archipelago. Its presence indicates the success of several decades of community-led conservation efforts in these waters to protect and expand seagrass meadows.

Here’s a delightfully odd capybara fact for you: they eat their own poop! While it may sound strange, digesting their food a second time helps them absorb nutrients that weren’t fully absorbed the first time. You could call this nature’s ultimate recycling program.

We recently asked WWF staff from across the organization to reflect on the work highlights that made 2025 meaningful.

WWF’s Sarah Davidson traveled to the Zambezi River and Victoria Falls, one of the seven natural wonders of the world, and shares why it’s so important to people and nature.
