Beavers are helping with climate change!

We can thank beavers for doing their part to keep our planet healthy! After being moved to a river in Washington, 69 beavers have begun to make serious changes in the environment. The beavers built 14 dams. Thanks to that work, the area has more water, and the water has gotten cooler. Why is this important? The extra water helps prevent fires and droughts, and the cooler water helps keep the salmon that live in the water alive!
