Clean Water Act, Then and Now (start time: 3:38): Two weeks ago was the 50th anniversary of the Clean Water Act. The landmark law set out to clean up the nation’s lakes, rivers and streams, and to safeguard the water supply for humans throughout the country. While there’s been some progress since the act was signed in 1972, many view the law as a mixed bag, both nationally and here in Colorado. By some estimates, at least half of the country’s rivers and streams do not meet the standard of the Clean Water Act. The legislation also faces new threats, including one from the U.S. Supreme Court. Host Susan Moran interviews two experts on the topic: John Flesher, a correspondent at the Associated Press; and Danny Katz is executive director of CoPIRG, which is part of the USPIRG network.

Today’s show features: Employing Beavers (start time: 11:12): Some consider them pests. Others praise them as saviors of the environment. Whatever your impression of these furry swimming rodents, beavers are gaining more proponents for their ability to make landscapes, and thus humans, more resilient to climate change. Through their dams and lodges, beavers raise water levels, moisten fire-prone forest soil, slow water speed, and thus prevent flooding while storing more water. Host Susan Moran talks with Jessica Doran, a wildlife biologist with EcoMetrics Colorado; and Aaron Hall, senior aquatic biologist with Defenders of Wildlife, about the promises and complexities of employing beavers as ecosystem engineers.

How On Earth 2018 interview with Eager author Ben Goldfarb Rewilding the American West (Ripple et al, BioScience, 2022)

Feature 1 – Flood Winners & Losers : Last month’s deluge cut canyons, real and felt, through many of our lives, but nature helps us remember that floods can build too. In this feature, How on Earth’s Jim Pullen speaks with Boulder’s wetland and riparian ecologist Marianne Giolitto about flood “winners and losers”. Marianne watches over 45,000 acres of the city’s open space and mountain parks wetlands and riparian habitats. Jim and the Boulder Open Space and Mountain Parks are working together on a series of radio vignettes; the first two are “Monitoring Bats” and “Great Storms and Chautauqua.”
Feature 2 – 100 Year Starship Symposium : Back in June we had a feature about a project called the 100 Year Star Ship. During that show we talked with Alires Almon, a member of the project, about the challenges and vision of creating a long-duration mission to send humans to another star. A few weeks ago in Houston, the project held their annual symposium; this year’s theme was titled: “Pathway to the Stars, Footprints on Earth.” Ms. Almon is back with us today to talk about the symposium and what new ideas were discussed.
