This model of letting trees grow back with little human influence could be implemented in other countries.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

New Jersey schools are working to make climate education widespread by implementing general education standards that include climate change education in every grade and subject.

Students at Catholic University of America in a net-zero design course are analyzing church structures and making suggestions for green improvements to address the climate crisis, reduce carbon emissions and support the Vatican’s Laudato Si’ mission to conserve energy and protect the planet. Though in its early days, the course has proven beneficial for U.S. dioceses, and students say it’s impacted the way they see architecture and design, and how it can have implications tied to the environment.
