In its first year, the second Trump Administration slashed environmental regulations and programs, overstepping its executive authority in the eyes of some environmental advocates. Pat Parenteau, who served as EPA regional counsel under President Reagan, talks with Host Aynsley O’Neill about the inability or reluctance of the judicial and legislative branches to provide a check on what he sees is abusive executive power that is threatening the health of people and planet.

The new Tropical Forest Forever Facility launched by Brazil at the 2025 UN climate talks is different from other efforts to protect nature in that it doesn’t rely on charity. Instead, it’s an investment fund that will pay dividends to both private investors and governments that keep their tropical and subtropical forest intact. Host Paloma Beltran walks Host Aynsley O’Neill through how it would work.

The American prairie is one of the most biodiverse ecosystems in the world, with numbers of species rivaling even a tropical rainforest. But today, just one percent of eastern tallgrass prairie remains, and western shortgrass prairie is disappearing at a rate of more than a million acres a year. Author Josephine Marcotty joins Host Paloma Beltran to discuss her book Sea of Grass: The Conquest, Ruin, and Redemption of Nature on the American Prairie.

Efforts to bring back bison are helping to revive Indigenous culture on lands across the US West. And as Colorado Public Radio’s Sam Brasch reports, this revival is taking place right in the city of Denver.

This June the US Environmental Protection Agency proposed eliminating regulations that limit climate changing gases from power plants, about a quarter of US emissions. Harvard Law Professor Richard Lazarus, an environmental and constitutional law scholar and author of The Rule of Five: Making Climate History at the Supreme Court, speaks with Host Steve Curwood about the perils of the broader Trump administration effort to weaken federal environmental protections.

As the host of this year’s UN climate treaty negotiations and home to most of the Amazon tropical rainforest, Brazil led a major advance for forests and their indigenous inhabitants called the Tropical Forest Forever Facility. The new $125 billion fund, with guarantees for investors, will send its profits to countries with documented forest preservation, including some cash going directly to indigenous and local populations. Michael Coe, a senior scientist at the Woodwell Climate Research Center who was at COP30, joins Hosts Steve Curwood and Jenni Doering to explain why forest protection is a vital piece of stabilizing the climate.
