This week, journalist Peter Dykstra and Host Steve Curwood take some time to reflect on some lives we lost in 2022. From Living on Earth's former producer Lucia Small to the infamous climate change skeptic Pat Michaels, the two discuss the passing of individuals who made their mark on the environmental sector, for better or for worse.

Coral reefs play a crucial role in managing tidal surges, creating habitat for other species, and improving water quality. But many oyster species including the Australian flat oyster are under threat. So, some scientists in Australia are looking into how baby oysters find an appropriate place to set up shop. Living on Earth’s Sophia Pandelidis has more on how sound may be key.

The case West Virginia v. EPA and the Inflation Reduction Act made 2022 a landmark year for environmental law. Pat Parenteau, former EPA regional counsel and emeritus professor at Vermont Law School, joins Host Steve Curwood to look ahead to environmental legal actions on the horizon in 2023, including Supreme Court clean water and other decisions, environmental justice implementation, and suits alleging climate racketeering.

Alligators have such gaping jaws you might wonder what they eat. For one group of researchers looking into this, the answers so far point to snails and amphibians like the giant salamanders known as amphiumas, rather than fish or hapless mammals that walk too close to swampy waters. Living on Earth’s Don Lyman spent a night in Florida’s Everglades with a team investigating this and shares his story.

Many non-human animals call cities home or take advantage of their abundant resources. In his 2022 book The Accidental Ecosystem: People and Wildlife in American Cities, environmental historian Peter Alagona explores how other species have found ways to live among us. He joins Host Jenni Doering to discuss how being more intentional about how we design and use our cities in the future can bring benefits for both humans and the wildlife we share these spaces with.
