World’s Largest Dam Removal Project Underway

An agreement finalized in November 2020 between farmers, tribes and dam owners will result in the deconstruction of four aging, inefficient dams along the Klamath River in the Pacific Northwest to restore salmon runs that have been in decline. The Karuk and Yurok tribes have relied on the salmon for both sustenance and spiritual well-being throughout their history. The project also signals a decline in the hydropower industry, which does not seem as profitable as predicted with the emergence of more cost-effective and sustainable energy sources such as wind and solar.

The World Commission on Dams released a report in November 2000 on the enormous financial, environmental and human costs and poor performance of large dams. The commission analyzed dozens of case studies and more than 1,000 testimonies regarding the outcome of trillions of dollars invested in dams. After decades of rapid construction, only 37 percent of the world’s rivers remain free-flowing. River fragmentation has heavily damaged freshwater habitats and fish stocks, threatening food security for millions of people and advancing the decline of other mammals, birds and reptiles.

Global Brief: Natural Thinking Spending Time in Nature Increases Cognitive Performance
More of our time is spent indoors than ever before. One of the ways by which nature may improve cognitive function (i.e. the acquisition of and goal-oriented use of knowledge) is by improving memory formation and recall, specifically that of short-term or working memory, and goal-oriented or directed attention; the kind that requires focused effort. By comparing and contrasting 13 studies, a team of researchers has shed light on this complex interaction in research published in Frontiers in Psychology. The studies used the backwards digit span task, which requires participants to invert a series of numbers and repeat them back. All demonstrated significantly improved cognition in nature as compared to urban environments. The benefits of studies like this are two-fold: not only are we learning more about how the brain interacts with its environment, but also how to leverage this interaction to lead healthier, more productive and happier lives.
