Learning to live with — and love — bears and eagles in Colombia's cloud forest

Some European schools have long championed free play in the woods as a way to combat the increasingly mainstream idea of "nature-deficit disorder." In Finland, enthusiastic teachers dedicate all of Friday to outdoor "secret" education - students don't even realize they are learning academic lessons. Inspired by these models, scattered American schools are experimenting with the idea, with some finding reductions in bullying and improvements in test scores and focus issues.

There used to be a time when oil spills devastated entire populations of animals. Although still an environmental disaster, scientists and wildlife veterinarians have become profoundly more successful at treating oiled birds. Crediting much of the success to better understanding the importance of order of treatment, rehabilitated birds are surviving at a much higher rate than ever before.

Researchers in Michigan are using the Archimedes screw, which is a rotating blade inside a cylinder, to transport fish upstream where there are barriers in the water.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

The nonprofit Coombs Outdoors runs summer and winter camps for youth to experience and learn about the outdoors. The camps are in high demand because of the affordable price made possible by donor subsidies.

A student-developed course at the University of California-Berkeley, Solutions for a Sustainable and Just Future, focuses on both individual and systemic strategies to address the climate crisis. More than 1,800 people have taken the class, and more than 70 percent of them said the course content inspired them to get involved in environmental work.

Led by Native Hawai’ians, Kamehameha Schools owns thousands of acres of land dedicated to stewardship and conservation. The school partners with Native Hawaiian organizations and conducts eco-cultural education programs for students and members of the community to foster connections between them and the environment.

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. These new education standards have been inspiring students to brainstorm solutions to climate-related issues like reducing food waste and increasing coastal resiliency. The state has also earmarked $5 million to help local teachers attend professional development sessions to teach them how to create new climate change-focused lesson plans.

As natural reefs continue to decline, artificial reefs constructed by humans from various materials like small stones or sunken ships create spaces for fish to breed safely.

Burdened by extreme drought, water diversions, and a lack of regulation, Lake Acuelo in Chile dried up. Now, researchers are learning from this slow-moving ecological disaster to help other lakes in trouble, like Utah’s Great Salt Lake.
